commit 19221e3083020bd9537624caa0ee0145ed92ba36 upstream.
The tegra_powergate_power_up() has a typo in the error code path where it
will try to disable clocks twice, fix it. In practice that error never
happens, so this is a minor correction.

commit fc153aba3ef371d0d76eb88230ed4e0dee5b38f2 upstream.
Instead of maintaining a single-linked list of devices that must be
searched linearly in .remove() just use spi_set_drvdata() to remember the
link between the spi device and the driver struct. Then the global list
and the next member can be dropped.
This simplifies the driver, reduces the memory footprint and the time to
search the list. Also it makes obvious that there is always a corresponding
driver struct for a given device in .remove(), so the error path for
!max3421_hcd can be dropped, too.
As a side effect this fixes a data inconsistency when .probe() races with
itself for a second max3421 device in manipulating max3421_hcd_list. A
similar race is fixed in .remove(), too.

and dvi connectors
commit bf552083916a7f8800477b5986940d1c9a31b953 upstream.
amdgpu_connector_vga_get_modes missed function amdgpu_get_native_mode
which assign amdgpu_encoder->native_mode with *preferred_mode result in
amdgpu_encoder->native_mode.clock always be 0. That will cause
amdgpu_connector_set_property returned early on:
if ((rmx_type != DRM_MODE_SCALE_NONE) &&
(amdgpu_encoder->native_mode.clock == 0))
when we try to set scaling mode Full/Full aspect/Center.
Add the missing function to amdgpu_connector_vga_get_mode can fix this.
It also works on dvi connectors because
amdgpu_connector_dvi_helper_funcs.get_mode use the same method.

using NETIF_F_LLTX:

immediately fail any slaves using that driver, and those slaves will stay

[ Upstream commit 321421b57a12e933f92b228e0e6d0b2c6541f41d ]
While issuing VF Reset from the guest OS, the VF driver prints
logs about critical / Overflow error detection. This is not an
actual error since the VF_MBX_ARQLEN register is set to all FF's
for a short period of time and the VF would catch the bits set if
it was reading the register during that spike of time.
This patch introduces an additional check to ignore this condition
since the VF is in reset.

[ Upstream commit 1283c0d1a32bb924324481586b5d6e8e76f676ba ]
We can't free the tg_pt_gp in core_alua_set_tg_pt_gp_id() because it's
still accessed via configfs. Its release must go through the normal
configfs/refcount process.
The max alua_tg_pt_gps_count check should probably have been done in
core_alua_allocate_tg_pt_gp(), but with the current code userspace could
have created 0x0000ffff + 1 groups, but only set the id for 0x0000ffff.
Then it could have deleted a group with an ID set, and then set the ID for
that extra group and it would work ok.
It's unlikely, but just in case this patch continues to allow that type of
behavior, and just fixes the kfree() while in use bug.

[ Upstream commit ed1227e080990ffec5bf39006ec8a57358e6689a ]
This patch fixes the following bugs:
1. If there are multiple ordered cmds queued and multiple simple cmds
completing, target_restart_delayed_cmds() could be called on different
CPUs and each instance could start a ordered cmd. They could then run in
different orders than they were queued.
2. target_restart_delayed_cmds() and target_handle_task_attr() can race
where:
1. target_handle_task_attr() has passed the simple_cmds == 0 check.
2. transport_complete_task_attr() then decrements simple_cmds to 0.
3. transport_complete_task_attr() runs target_restart_delayed_cmds() and
it does not see any cmds on the delayed_cmd_list.
4. target_handle_task_attr() adds the cmd to the delayed_cmd_list.
The cmd will then end up timing out.
3. If we are sent > 1 ordered cmds and simple_cmds == 0, we can execute
them out of order, because target_handle_task_attr() will hit that
simple_cmds check first and return false for all ordered cmds sent.
4. We run target_restart_delayed_cmds() after every cmd completion, so if
there is more than 1 simple cmd running, we start executing ordered cmds
after that first cmd instead of waiting for all of them to complete.
5. Ordered cmds are not supposed to start until HEAD OF QUEUE and all older
cmds have completed, and not just simple.
6. It's not a bug but it doesn't make sense to take the delayed_cmd_lock
for every cmd completion when ordered cmds are almost never used. Just
replacing that lock with an atomic increases IOPs by up to 10% when
completions are spread over multiple CPUs and there are multiple
sessions/ mqs/thread accessing the same device.
This patch moves the queued delayed handling to a per device work to
serialze the cmd executions for each device and adds a new counter to track
HEAD_OF_QUEUE and SIMPLE cmds. We can then check the new counter to
determine when to run the work on the completion path.

In the testcase pty04, The first process call the write syscall to send
data to the pty master. At the same time, the workqueue will do the
flush_to_ldisc to pop data in a loop until there is no more data left.
When the sender and workqueue running in different core, the sender sends
data fastly in full time which will result in workqueue doing work in loop
for a long time and occuring softlockup in flush_to_ldisc with kernel
configured without preempt. So I add need_resched check and cond_resched
in the flush_to_ldisc loop to avoid it.

[ Upstream commit 99154581b05c8fb22607afb7c3d66c1bace6aa5d ]
When parsing the txq list in lpfc_drain_txq(), the driver attempts to pass
the requests to the adapter. If such an attempt fails, a local "fail_msg"
string is set and a log message output. The job is then added to a
completions list for cancellation.
Processing of any further jobs from the txq list continues, but since
"fail_msg" remains set, jobs are added to the completions list regardless
of whether a wqe was passed to the adapter. If successfully added to
txcmplq, jobs are added to both lists resulting in list corruption.
Fix by clearing the fail_msg string after adding a job to the completions
list. This stops the subsequent jobs from being added to the completions
list unless they had an appropriate failure.

Put new_slave in bond_sysfs_slave_add() will cause use-after-free problems
when new_slave is accessed in the subsequent error handling process. Since
new_slave will be put in the subsequent error handling process, remove the
unnecessary put to fix it.
In addition, when sysfs_create_file() fails, if some files have been crea-
ted successfully, we need to call sysfs_remove_file() to remove them.
Since there are sysfs_create_files() & sysfs_remove_files() can be used,
use these two functions instead.

[ Upstream commit 009a789443fe4c8e6b1ecb7c16b4865c026184cd ]
The handling of PMIC register reads through writing 0 to address 4
of the OpRegion is wrong. Instead of returning the read value
through the value64, which is a no-op for function == ACPI_WRITE calls,
store the value and then on a subsequent function == ACPI_READ with
address == 3 (the address for the value field of the OpRegion)
return the stored value.
This has been tested on a Xiaomi Mi Pad 2 and makes the ACPI battery dev
there mostly functional (unfortunately there are still other issues).
Here are the SET() / GET() functions of the PMIC ACPI device,
which use this OpRegion, which clearly show the new behavior to
be correct:
OperationRegion (REGS, 0x8F, Zero, 0x50)
Field (REGS, ByteAcc, NoLock, Preserve)
{
CLNT, 8,
SA, 8,
OFF, 8,
VAL, 8,
RWM, 8
}
Method (GET, 3, Serialized)
{
If ((AVBE == One))
{
CLNT = Arg0
SA = Arg1
OFF = Arg2
RWM = Zero
If ((AVBG == One))
{
GPRW = Zero
}
}
Return (VAL) /* \_SB_.PCI0.I2C7.PMI5.VAL_ */
}
Method (SET, 4, Serialized)
{
If ((AVBE == One))
{
CLNT = Arg0
SA = Arg1
OFF = Arg2
VAL = Arg3
RWM = One
If ((AVBG == One))
{
GPRW = One
}
}

This patch allows to use 0 for `coal->rx_coalesce_usecs` param to
disable rx irq coalescing.
Previously we could enable rx irq coalescing via ethtool
(For ex: `ethtool -C eth0 rx-usecs 2000`) but we couldn't disable
it because this part rejects 0 value:

A successful 'clk_prepare()' call should be balanced by a corresponding
'clk_unprepare()' call in the error handling path of the probe, as already
done in the remove function.
More specifically, 'clk_prepare_enable()' is used, but 'clk_disable()' is
also already called. So just the unprepare step has still to be done.
Update the error handling path accordingly.

[ Upstream commit e7e1e880b114ca640a2f280b0d5d38aed98f98c6 ]
Before the `callback_result` callback was introduced drivers coded their
invocation to the callback in a similar way to:
if (cb->callback) {
spin_unlock(&dma->lock);
cb->callback(cb->callback_param);
spin_lock(&dma->lock);
}
With the introduction of `callback_result` two helpers where introduced to
transparently handle both types of callbacks. And drivers where updated to
look like this:
if (dmaengine_desc_callback_valid(cb)) {
spin_unlock(&dma->lock);
dmaengine_desc_callback_invoke(cb, ...);
spin_lock(&dma->lock);
}
dmaengine_desc_callback_invoke() correctly handles both `callback_result`
and `callback`. But we forgot to update the dmaengine_desc_callback_valid()
function to check for `callback_result`. As a result DMA descriptors that
use the `callback_result` rather than `callback` don't have their callback
invoked by drivers that follow the pattern above.
Fix this by checking for both `callback` and `callback_result` in
dmaengine_desc_callback_valid().

does not need explicit safeguards, the user can still write a single
newline to an attribute file:
echo > .../message

empty string, and causing an infinite loop in img_ascii_lcd_scroll().

one is encountered.
