In case of drv own fail in reset, we may need to run mac_reset several
times. The sequence would trigger system crash as the log below.
Because we do not re-enable/schedule "tx_napi" before disable it again,
the process would keep waiting for state change in napi_diable(). To
avoid the problem and keep status synchronize for each run, goto final
resource handling if drv own failed.

It was observed that on a Thinkpad T14 Gen1 (AMD) that the platform
profile is starting up in 'low-power' mode after refreshing what the
firmware had. This is most likely a firmware bug, but as a harmless
workaround set the default profile to 'balanced' at thinkpad_acpi startup.

When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll
function immediately returns an error.
This is incorrect for two reasons:
* the function terminates without enabling interrupts or scheduling NAPI,
* the error code (-ENOMEM) is returned instead of the number of received
packets.
After the first memory allocation failure occurs, packet reception is
locked due to disabled interrupts from DMA..

This is a follow-up to the discussion in [0]. It seems to me that
at least the IP version used on Amlogic SoC's sometimes has a problem
if register MAC_CTRL_REG is written whilst the chip is still processing
a previous write. But that's just a guess.
Adding a delay between two writes to this register helps, but we can
also simply omit the offending second write. This patch uses the second
approach and is based on a suggestion from Qi Duan.
Benefit of this approach is that we can save few register writes, also
on not affected chip versions.

Assign a random mac address to the VF interface station
address if it boots with a zero mac address in order to match
similar behavior seen in other VF drivers. Handle the errors
where the older firmware does not allow the VF to set its own
station address.
Newer firmware will allow the VF to set the station mac address
if it hasn't already been set administratively through the PF.
Setting it will also be allowed if the VF has trust.

In looping on FW update tests we occasionally see the
FW_ACTIVATE_STATUS command fail while it is in its EAGAIN loop
waiting for the FW activate step to finsh inside the FW. The
firmware is complaining that the done bit is set when a new
dev_cmd is going to be processed.
Doing a clean on the cmd registers and doorbell before exiting
the wait-for-done and cleaning the done bit before the sleep
prevents this from occurring.

There is a case found in heavy testing where a link flap happens just
before a firmware Recovery event and the driver gets stuck in the
BROKEN state. This comes from the driver getting interrupted by a FW
generation change when coming back up from the link flap, and the call
to ionic_start_queues() in ionic_link_status_check() fails. This can be
addressed by having the fw_up code clear the BROKEN bit if seen, rather
than waiting for a user to manually force the interface down and then
back up.

This string was introduced because drivers for NVIDIA hardware
had bugs supporting RTD3 in the past.
Before proprietary NVIDIA driver started to support RTD3, Ubuntu had
had a mechanism for switching PRIME on and off, though it had required
to logout/login to make the library switch happen.
When the PRIME had been off, the mechanism had unloaded the NVIDIA
driver and put the device into D3cold, but the GPU had never come back
to D0 again which is why ODMs used the _OSI to expose an old _DSM
method to switch the power on/off.
That has been fixed by commit 5775b843a619 ("PCI: Restore config space
on runtime resume despite being unbound"). so vendors shouldn't be
using this string to modify ASL any more.

After xHC controller is started, either in probe or resume, it can take
a while before any of the connected usb devices are visible to the roothub
due to link training.
It's possible xhci driver loads, sees no acivity and suspends the host
before the USB device is visible.
In one testcase with a hotplugged xHC controller the host finally detected
the connected USB device and generated a wake 500ms after host initial
start.
If hosts didn't suspend the device duringe training it probablty wouldn't
take up to 500ms to detect it, but looking at specs reveal USB3 link
training has a couple long timeout values, such as 120ms
RxDetectQuietTimeout, and 360ms PollingLFPSTimeout.
So Add a 500ms grace period that keeps polling the roothub for 500ms after
start, preventing runtime suspend until USB devices are detected.

The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.
Additionally lock_pages() doesn't check for pin_user_pages_fast()
having been completely successful, resulting in potentially not
locking all pages into memory. This could result in sporadic failures
when using the related memory in user mode.
Fix all of that by calling unlock_pages() always with the real number
of pinned pages, which will be zero in case pages being NULL, and by
checking the number of pages pinned by pin_user_pages_fast() matching
the expected number of pages.

We can dereference a null pointer trying to queue work to a destroyed
workqueue.
If the device is disconnected, nintendo_hid_remove is called, in which
the rumble_queue is destroyed. Avoid using that queue to defer rumble
work once the controller state is set to JOYCON_CTLR_STATE_REMOVED.

Switching between falling/rising edges for IRQ_TYPE_EDGE_BOTH on pins that
require debounce can cause the device to lose events due to a desync
between pin state and irq type.
This problem is resolved by switching between IRQ_TYPE_LEVEL_LOW and
IRQ_TYPE_LEVEL_HIGH instead.

Make acpi_cpc_valid() check if ACPI is disabled, so that its callers
don't need to check that separately. This will also cause the AMD
pstate driver to refuse to load right away when ACPI is disabled.
Also update the warning message in amd_pstate_init() to mention the
ACPI disabled case for completeness.

pfuze100_regulator_probe()
The pfuze_chip::regulator_descs is an array of size
PFUZE100_MAX_REGULATOR, the pfuze_chip::pfuze_regulators
is the pointer to the real regulators of a specific device.
The number of real regulator is supposed to be less than
the PFUZE100_MAX_REGULATOR, so we should use the size of
'regulator_num * sizeof(struct pfuze_regulator)' in memcpy().
This fixes the out of bounds access bug reported by KASAN.

ACPI node pointers are attached to data node handles, in order to resolve
string references to them. _DSD guide allows the same node to be reached
from multiple parent nodes, leading the node enumeration algorithm to each
such nodes more than once. As attached data already already exists,
attaching data with the same tag will fail. Address this problem by
ignoring nodes that have been already tagged.

The current code expects the type of the value to be an integer type,
instead the value passed to the macro is a pointer.

max value, instead of using the integer type.

Previously when we added a fence to a dma_resv object we always
assumed the the newer than all the existing fences.
With Jason's work to add an UAPI to explicit export/import that's not
necessary the case any more. So without this check we would allow
userspace to force the kernel into an use after free error.
Since the change is very small and defensive it's probably a good
idea to backport this to stable kernels as well just in case others
are using the dma_resv object in the same way.

commit 87562fcd1342 ("HID: input: remove the need for HID_QUIRK_INVERT")
made the assumption that it was the only one handling tablets and thus
kept an internal state regarding the tool.
Turns out that the uclogic driver has a timer to release the in range
bit, effectively making hid-input ignoring all in range information
after the very first one.
Fix that by having a more rationale approach which consists in forwarding
every event and let the input stack filter out the duplicates.

The touchbar on Apple T2 Macs has 2 modes, one that shows the function
keys and other that shows the media controls. The user can use the fn
key on his keyboard to switch between the 2 modes.
On Linux, if people were using an external keyboard or mouse, the
touchbar failed to change modes on pressing the fn key with the following
in dmesg :-

Similar to the Surface Go devices, the Elantech touchscreen/digitizer in
the Lenovo Yoga C630 mistakenly reports the battery of the stylus, and
always reports an empty battery.
Apply the HID_BATTERY_QUIRK_IGNORE quirk to ignore this battery and
prevent the erroneous low battery warnings.
