commit 107927fa597c99eaeee4f51865ca0956ec71b6a2 upstream.
In imx_media_create_csi_of_links(), the 'struct v4l2_fwnode_link' must
be cleared for each endpoint iteration, otherwise if the remote port
has no "reg" property, link.remote_port will not be reset to zero.
This was discovered on the i.MX53 SMD board, since the OV5642 connects
directly to ipu1_csi0 and has a single source port with no "reg"
property.

commit 904371f90b2c0c749a5ab75478c129a4682ac3d8 upstream.
On i.MX6, the nearest upstream entity to the CSI can only be the
CSI video muxes or the Synopsys DW MIPI CSI-2 receiver.
However the i.MX53 has no CSI video muxes or a MIPI CSI-2 receiver.
So allow for the nearest upstream entity to the CSI to be something
other than those.

commit af708900e9a48c0aa46070c8a8cdf0608a1d2025 upstream.
It looks like v4.18-rc1 commit [0] which upstreams mld-1.8.0
commit [1] missed to fix the memory leak in mod_exit function.
Do it now.

commit 47830c1127ef166af787caf2f871f23089610a7f upstream.
Since moving the message buffers off the stack, the dynamically
allocated get-prop-descriptor request buffer is incorrectly sized due to
using the pointer rather than request-struct size when creating the
operation.
Fortunately, the pointer size is always larger than this one-byte
request, but this could still cause trouble on the remote end due to the
unexpected message size.

commit 78accaea117c1ae878774974fab91ac4a0b0e2b0 upstream.
The lsb calculation is not masking the correct bits from the user input.
Subtract 1 from (1 << offset) to correctly set up the mask to be applied
to user input.
The lsb register stores its value starting at the bit 7 position.
adt7316_store_DAC() currently assumes the value is at the other end of the
register. Shift the lsb value before storing it in a new variable lsb_reg,
and write this variable to the lsb register.

commit 76b7fe8d6c4daf4db672eb953c892c6f6572a282 upstream.
The adt7316/7 and adt7516/7 have the option to output voltage proportional
to temperature on dac a and/or dac b. The default dac resolution in this
mode is 8 bits with the dac high resolution option enabling 10 bits. None
of these settings affect dacs c and d. Remove the "1 (12 bits)" output from
the show function since that is not an option for this mode. Return
"1 (10 bits)" if the device is one of the above mentioned chips and the dac
high resolution mode is enabled.
In the store function, the driver currently allows the user to write to the
ADT7316_DA_HIGH_RESOLUTION bit regardless of the device in use. Add a check
to return an error in the case of an adt7318 or adt7519. Remove the else
statement that clears the ADT7316_DA_HIGH_RESOLUTION bit. Instead, clear it
before conditionally enabling it, depending on user input. This matches the
typical pattern in the driver when an attribute is a boolean.

commit 45130fb030aec26ac28b4bb23344901df3ec3b7f upstream.
The calculation of the current dac value is using the wrong bits of the
dac lsb register. Create two macros to shift the lsb register value into
lsb position, depending on whether the dac is 10 or 12 bit. Initialize
data to 0 so, with an 8 bit dac, the msb register value can be bitwise
ORed with data.

[ Upstream commit 22c971db7dd4b0ad8dd88e99c407f7a1f4231a2e ]
Colin King reported a bug in read_bbreg_hdl():
memcpy(pcmd->rsp, (u8 *)&val, pcmd->rspsz);
The problem is that "val" is uninitialized.
This code is obviously not useful, but so far as I can tell
"pcmd->cmdcode" is never GEN_CMD_CODE(_Read_BBREG) so it's not harmful
either. For now the easiest fix is to just call r8712_free_cmd_obj()
and return.

[ Upstream commit 1beea6204e2304dd11600791d8dad8e7350af6ad ]
When building without CONFIG_OF, the compiler loses track of the flow
control in axis_fifo_probe(), and thinks that many variables are used
without an initialization even though we actually leave the function
before the first use:
drivers/staging/axis-fifo/axis-fifo.c: In function 'axis_fifo_probe':
drivers/staging/axis-fifo/axis-fifo.c:900:5: error: 'rxd_tdata_width' may be used uninitialized in this function [-Werror=maybe-uninitialized]

When CONFIG_OF is set, this does not happen, and since the driver cannot
work without it, just add that option as a Kconfig dependency.

commit af4b54a2e5ba18259ff9aac445bf546dd60d037e upstream.
`ni6501_alloc_usb_buffers()` is called from `ni6501_auto_attach()` to
allocate RX and TX buffers for USB transfers. It allocates
`devpriv->usb_rx_buf` followed by `devpriv->usb_tx_buf`. If the
allocation of `devpriv->usb_tx_buf` fails, it frees
`devpriv->usb_rx_buf`, leaving the pointer set dangling, and returns an
error. Later, `ni6501_detach()` will be called from the core comedi
module code to clean up. `ni6501_detach()` also frees both
`devpriv->usb_rx_buf` and `devpriv->usb_tx_buf`, but
`devpriv->usb_rx_buf` may have already beed freed, leading to a
double-free error. Fix it bu removing the call to
`kfree(devpriv->usb_rx_buf)` from `ni6501_alloc_usb_buffers()`, relying
on `ni6501_detach()` to free the memory.

commit 660cf4ce9d0f3497cc7456eaa6d74c8b71d6282c upstream.
If `ni6501_auto_attach()` returns an error, the core comedi module code
will call `ni6501_detach()` to clean up. If `ni6501_auto_attach()`
successfully allocated the comedi device private data, `ni6501_detach()`
assumes that a `struct mutex mut` contained in the private data has been
initialized and uses it. Unfortunately, there are a couple of places
where `ni6501_auto_attach()` can return an error after allocating the
device private data but before initializing the mutex, so this
assumption is invalid. Fix it by initializing the mutex just after
allocating the private data in `ni6501_auto_attach()` before any other
errors can be retturned. Also move the call to `usb_set_intfdata()`
just to keep the code a bit neater (either position for the call is
fine).
I believe this was the cause of the following syzbot crash report

[ Upstream commit e9de475723de5bf207a5b7b88bdca863393e42c8 ]
The value of dac_bits is used in adt7316_show_DAC() and adt7316_store_DAC(),
and it should be either 8, 10, or 12 bits depending on the device in use. The
driver currently only assigns a value to dac_bits in
adt7316_store_da_high_resolution(). The purpose of the dac high resolution
option is not to change dac resolution for normal operation. Instead, it
is specific to an optional feature where one or two of the four dacs can
be set to output voltage proportional to temperature. If the user chooses
to set dac a and/or dac b to output voltage proportional to temperature,
the da_high_resolution attribute can optionally be enabled to use 10 bit
resolution rather than the default 8 bits. This is only available on the
10 and 12 bit dac devices. If the user attempts to read or write dacs a
or b under these settings, the driver's current behaviour is to return an
error. Dacs c and d continue to operate normally under these conditions.
With the above in mind, remove the dac_bits assignments from this function
since the value of dac_bits as used in the driver is not dependent on this
dac high resolution option.
Since the dac_bits assignments discussed above are currently the only ones
in this driver, the default value of dac_bits is 0. This results in incorrect
calculations when the dacs are read or written in adt7316_show_DAC() and
adt7316_store_DAC(). To correct this, assign a value to dac_bits in
adt7316_probe() to ensure correct operation as soon as the device is
registered and available to userspace.

[ Upstream commit 29701c3612fa025d5e8dc64c7a4ae8dc4763912e ]
Fix the assigned type of mem2mem buffer handling API.
Namely, these functions:
v4l2_m2m_next_buf
v4l2_m2m_last_buf
v4l2_m2m_buf_remove
v4l2_m2m_next_src_buf
v4l2_m2m_next_dst_buf

v4l2_m2m_last_dst_buf
v4l2_m2m_src_buf_remove
v4l2_m2m_dst_buf_remove
return a struct vb2_v4l2_buffer, and not a struct vb2_buffer.
Fixing this is necessary to fix the mem2mem buffer handling API,
changing the return to the correct struct vb2_v4l2_buffer instead
of a void pointer.

commit b6391ac73400eff38377a4a7364bd3df5efb5178 upstream.
Complete read error handling paths for all three kinds of
compressed pages:
1) For cache-managed pages, PG_uptodate will be checked since
read_endio will unlock and SetPageUptodate for these pages;
2) For inplaced pages, read_endio cannot SetPageUptodate directly
since it should be used to mark the final decompressed data,
PG_error will be set with page locked for IO error instead;
3) For staging pages, PG_error is used, which is similar to
what we do for inplaced pages.

out of the workqueue while the interrupt is disabled by continuous polling
by it.
Move MACvIntEnable to vnt_interrupt_work so that it is always enabled

Move MACvIntDisable so that the device doesn't keep polling the system
while the workqueue is being processed.

When switching from speakup_soft to another synth, speakup_soft would
keep calling synth_buffer_getc() from softsynthx_read.
Let's thus make synth.c export the knowledge of the current synth, so
that speakup_soft can determine whether it should be running.
speakup_soft also needs to set itself alive, otherwise the switch would
let it remain silent.

commit bafd9c64056cd034a1174dcadb65cd3b294ff8f6 upstream.
`ni_cdio_cmdtest()` validates Comedi asynchronous commands for the DIO
subdevice (subdevice 2) of supported National Instruments M-series
cards. It is called when handling the `COMEDI_CMD` and `COMEDI_CMDTEST`
ioctls for this subdevice. There are two causes for a possible
divide-by-zero error when validating that the `stop_arg` member of the
passed-in command is not too large.
The first cause for the divide-by-zero is that calls to
`comedi_bytes_per_scan()` are only valid once the command has been
copied to `s->async->cmd`, but that copy is only done for the
`COMEDI_CMD` ioctl. For the `COMEDI_CMDTEST` ioctl, it will use
whatever was left there by the previous `COMEDI_CMD` ioctl, if any.
(This is very likely, as it is usual for the application to use
`COMEDI_CMDTEST` before `COMEDI_CMD`.) If there has been no previous,
valid `COMEDI_CMD` for this subdevice, then `comedi_bytes_per_scan()`
will return 0, so the subsequent division in `ni_cdio_cmdtest()` of
`s->async->prealloc_bufsz / comedi_bytes_per_scan(s)` will be a
divide-by-zero error. To fix this error, call a new function
`comedi_bytes_per_scan_cmd(s, cmd)`, based on the existing
`comedi_bytes_per_scan(s)` but using a specified `struct comedi_cmd` for
its calculations. (Also refactor `comedi_bytes_per_scan()` to call the
new function.)
Once the first cause for the divide-by-zero has been fixed, the second
cause is that `comedi_bytes_per_scan_cmd()` can legitimately return 0 if
the `scan_end_arg` member of the `struct comedi_cmd` being tested is 0.
Fix it by only performing the division (and validating that `stop_arg`
is no more than the maximum value) if `comedi_bytes_per_scan_cmd()`
returns a non-zero value.
The problem was reported on the COMEDI mailing list here:

Move upstream stream off to just after receiving the last EOF completion
and disabling the CSI (and thus before disabling the IDMA channel) in
csi_stop(). For symmetry also move upstream stream on to beginning of
csi_start().
Doing this makes csi_s_stream() more symmetric with prp_s_stream() which
will require the same change to fix a hard lockup.

commit 2e0fe66e0a136252f4d89dbbccdcb26deb867eb8 upstream.
Disable the CSI immediately after receiving the last EOF before stream
off (and thus before disabling the IDMA channel). Do this by moving the
wait for EOF completion into a new function csi_idmac_wait_last_eof().
This fixes a complete system hard lockup on the SabreAuto when streaming
from the ADV7180, by repeatedly sending a stream off immediately followed
by stream on:
while true; do v4l2-ctl -d4 --stream-mmap --stream-count=3; done
Eventually this either causes the system lockup or EOF timeouts at all
subsequent stream on, until a system reset.
The lockup occurs when disabling the IDMA channel at stream off. Disabling
the CSI before disabling the IDMA channel appears to be a reliable fix for
the hard lockup.

commit a19c22677377b87e4354f7306f46ad99bc982a9f upstream.
Upstream must be stopped immediately after receiving the last EOF and
before disabling the IDMA channel. This can be accomplished by moving
upstream stream off to just after receiving the last EOF completion in
prp_stop(). For symmetry also move upstream stream on to end of
prp_start().
This fixes a complete system hard lockup on the SabreAuto when streaming

by stream on:
while true; do v4l2-ctl -d1 --stream-mmap --stream-count=3; done
Eventually this either causes the system lockup or EOF timeouts at all
subsequent stream on, until a system reset.
The lockup occurs when disabling the IDMA channel at stream off. Stopping
the video data stream entering the IDMA channel before disabling the
channel itself appears to be a reliable fix for the hard lockup.

z_erofs_vle_unzip:
...
for (i = 0; i < nr_pages; ++i) {

z_erofs_onlinepage_endio(page); (1)

continue;
/* recycle all individual staging pages */
(void)z_erofs_gather_if_stagingpage(page_pool, page); (3)

}
...
After (1) is executed, page is freed and could be then reused, if
compressed_pages is scanned after that, it could fall info (2) or
(3) by mistake and that could finally be in a mess.
This patch aims to solve the above issue only with little changes
as much as possible in order to make the fix backport easier.
