[ Upstream commit 928edefbc18cd8433f7df235c6e09a9306e7d580 ]
This looks really unusual to have a 'get_device()' hidden in a 'dev_err()'
call.
Remove it.
While at it add a missing \n at the end of the message.

commit ffca476a0a8d26de767cc41d62b8ca7f540ecfdd upstream.
In the case of get_user_pages_fast() returning fewer pages than
requested, rio_dma_transfer() does not quite do the right thing. It
attempts to release all the pages that were requested, rather than just
the pages that were pinned.
Fix the error handling so that only the pages that were successfully
pinned are released.

commit 34625c1931f8204c234c532b446b9f53c69f4b68 upstream.
In the "gb_tty_set_termios" function the "newline" variable is declared
but not initialized. So the "flow_control" member is not initialized and
the OR / AND operations with itself results in an undefined value in
this member.
The purpose of the code is to set the flow control type, so remove the
OR / AND self operator and set the value directly.

commit 5e4f99a6b788047b0b8a7496c2e0c8f372f6edf2 upstream.
If the serial interface is used, the 8-bit address should be latched using
the rising edge of the WR/FSYNC signal.
This basically means that a CS change is required between the first byte
sent, and the second one.
This change splits the single-transfer transfer of 2 bytes into 2 transfers
with a single byte, and CS change in-between.
Note fixes tag is not accurate, but reflects a point beyond which there
are too many refactors to make backporting straight forward.

commit 98e2630284ab741804bd0713e932e725466f2f84 upstream.
Currently the kfree of output.pointer can be potentially freeing
an uninitalized pointer in the case where out_data is NULL. Fix this
by reworking the case where out_data is not-null to perform the
ACPI status check and also the kfree of outpoint.pointer in one block
and hence ensuring the pointer is only freed when it has been used.
Also replace the if (ptr != NULL) idiom with just if (ptr).

Commit b53611fb1ce9 ("dmaengine: tegra210-adma: Fix crash during probe")

that all resources are released.

commit 72139dfa2464e43957d330266994740bb7be2535 upstream.
The struct cdev is embedded in the struct watchdog_core_data. In the
current code, we manage the watchdog_core_data with a kref, but the
cdev is manged by a kobject. There is no any relationship between
this kref and kobject. So it is possible that the watchdog_core_data is
freed before the cdev is entirely released. We can easily get the
following call trace with CONFIG_DEBUG_KOBJECT_RELEASE and
CONFIG_DEBUG_OBJECTS_TIMERS enabled.

This is a common issue when using cdev embedded in a struct.
Fortunately, we already have a mechanism to solve this kind of issue.
Please see commit 233ed09d7fda ("chardev: add helper function to
register char devs with a struct device") for more detail.
In this patch, we choose to embed the struct device into the
watchdog_core_data, and use the API provided by the commit 233ed09d7fda
to make sure that the release of watchdog_core_data and cdev are
in sequence.

[ Upstream commit 1413ef638abae4ab5621901cf4d8ef08a4a48ba6 ]
The struct cdev is embedded in the struct i2c_dev. In the current code,
we would free the i2c_dev struct directly in put_i2c_dev(), but the
cdev is manged by a kobject, and the release of it is not predictable.
So it is very possible that the i2c_dev is freed before the cdev is
entirely released. We can easily get the following call trace with

This is a common issue when using cdev embedded in a struct.
Fortunately, we already have a mechanism to solve this kind of issue.
Please see commit 233ed09d7fda ("chardev: add helper function to
register char devs with a struct device") for more detail.
In this patch, we choose to embed the struct device into the i2c_dev,
and use the API provided by the commit 233ed09d7fda to make sure that
the release of i2c_dev and cdev are in sequence.

[ Upstream commit 3bd12da7f50b8bc191fcb3bab1f55c582234df59 ]
asus-nb-wmi does not add any extra functionality on these Asus
Transformer books. They have detachable keyboards, so the hotkeys are
send through a HID device (and handled by the hid-asus driver) and also
the rfkill functionality is not used on these devices.
Besides not adding any extra functionality, initializing the WMI interface
on these devices actually has a negative side-effect. For some reason
the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives
GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED,
high and there is no (WMI or other) interface to drive this low again
causing the LED to be permanently on, even during suspend.
This commit adds a blacklist of DMI system_ids on which not to load the
asus-nb-wmi and adds these Transformer books to this list. This fixes
the webcam LED being permanently on under Linux.

[ Upstream commit ac854131d9844f79e2fdcef67a7707227538d78a ]
The syzbot fuzzer found a race between URB submission to endpoint 0
and device reset. Namely, during the reset we call usb_ep0_reinit()
because the characteristics of ep0 may have changed (if the reset
follows a firmware update, for example). While usb_ep0_reinit() is
running there is a brief period during which the pointers stored in
udev->ep_in[0] and udev->ep_out[0] are set to NULL, and if an URB is
submitted to ep0 during that period, usb_urb_ep_type_check() will
report it as a driver bug. In the absence of those pointers, the
routine thinks that the endpoint doesn't exist. The log message looks
like this:
------------[ cut here ]------------
usb 2-1: BOGUS urb xfer, pipe 2 != type 2
WARNING: CPU: 0 PID: 9241 at drivers/usb/core/urb.c:478
usb_submit_urb+0x1188/0x1460 drivers/usb/core/urb.c:478
Now, although submitting an URB while the device is being reset is a
questionable thing to do, it shouldn't count as a driver bug as severe
as submitting an URB for an endpoint that doesn't exist. Indeed,
endpoint 0 always exists, even while the device is in its unconfigured
state.
To prevent these misleading driver bug reports, this patch updates
usb_disable_endpoint() to avoid clearing the ep_in[] and ep_out[]
pointers when the endpoint being disabled is ep0. There's no danger
of leaving a stale pointer in place, because the usb_host_endpoint
structure being pointed to is stored permanently in udev->ep0; it
doesn't get deallocated until the entire usb_device structure does.

[ Upstream commit e461b8c991b9202b007ea2059d953e264240b0c9 ]
IVRS parsing code always tries to read 255 bytes from memory when
retrieving ACPI device path, and makes an assumption that firmware
provides a zero-terminated string. Both of those are bugs: the entry
is likely to be shorter than 255 bytes, and zero-termination is not
guaranteed.
With Acer SF314-42 firmware these issues manifest visibly in dmesg:
AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR0\xf0\xa5, rdevid:160
AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR1\xf0\xa5, rdevid:160
AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR2\xf0\xa5, rdevid:160
AMD-Vi: ivrs, add hid:AMDI0020, uid:\_SB.FUR3>\x83e\x8d\x9a\xd1...
The first three lines show how the code over-reads adjacent table
entries into the UID, and in the last line it even reads garbage data
beyond the end of the IVRS table itself.
Since each entry has the length of the UID (uidl member of ivhd_entry
struct), use that for memcpy, and manually add a zero terminator.
Avoid zero-filling hid and uid arrays up front, and instead ensure
the uid array is always zero-terminated. No change needed for the hid
array, as it was already properly zero-terminated.

On platforms with IOMMU enabled, multiple SGs can be coalesced into one

The above NULL pointer dereference is the result of block_len and the
sent_len set to zero after the first SG of the list when IOMMU driver
is enabled. Because of this the loop of processing the SGs has run
more than num_sgs which resulted in a sg_next on the last SG of the
list which has SG_END set.
Fix this by check for the sg before any attributes of the sg are
accessed.

commit 15753588bcd4bbffae1cca33c8ced5722477fe1f upstream.
FuzzUSB (a variant of syzkaller) found an illegal array access
using an incorrect index while binding a gadget with UDC.
Reference: https://www.spinics.net/lists/linux-usb/msg194331.html
This bug occurs when a size variable used for a buffer
is misused to access its strcpy-ed buffer.
Given a buffer along with its size variable (taken from user input),
from which, a new buffer is created using kstrdup().
Due to the original buffer containing 0 value in the middle,
the size of the kstrdup-ed buffer becomes smaller than that of the original.
So accessing the kstrdup-ed buffer with the same size variable
triggers memory access violation.
The fix makes sure no zero value in the buffer,
by comparing the strlen() of the orignal buffer with the size variable,
so that the access to the kstrdup-ed buffer is safe.
