All of these cases are perfectly valid and good traditional C, but hit
by the "you're not NUL-terminating your byte array" warning.
And none of the cases want any terminating NUL character.
Mark them __nonstring to shut up gcc-15 (and in the case of the ak8974
magnetometer driver, I just removed the explicit array size and let gcc
expand the 3-byte and 6-byte arrays by one extra byte, because it was
the simpler change).

The current reset pulse width is measured to be 5us on a
Renesas RZ/G2L SOM. The manufacturer's minimum reset pulse width is
specified as 10us.
Extend reset pulse width to make sure it is long enough on all platforms.
Also reword confusing comments about reset pin assertion.

For a setup where the matrix keypad is connected over a slow interface
(e.g. a gpio-expansion over i2c), the scan can take a longer time to read.
Interrupts need to be disabled during scan. And therefore changes in this
period are not detected.
To improve this situation, scan the matrix again if the row state changed
during interrupts disabled.
The rescan is repeated until no change is detected anymore.

Pull timer cleanups from Thomas Gleixner:
"A set of final cleanups for the timer subsystem:
- Convert all del_timer[_sync]() instances over to the new
timer_delete[_sync]() API and remove the legacy wrappers.
Conversion was done with coccinelle plus some manual fixups as
coccinelle chokes on scoped_guard().
- The final cleanup of the hrtimer_init() to hrtimer_setup()
conversion.
This has been delayed to the end of the merge window, so that all
patches which have been merged through other trees are in mainline
and all new users are catched.
Doing this right before rc1 ensures that new code which is merged post
rc1 is not introducing new instances of the original functionality"

In cyapa_update_fw_store(), if 'count' is zero, the write to
fw_name[count-1] underflows the array.
Presumably that's not possible in normal operation, as its caller
sysfs_kf_write() already checks for zero. Regardless it's a good idea
to check for the error explicitly and avoid undefined behavior.

The current implementation of the goodix_berlin driver lacks support for
revisions A and B of the Berlin IC. This change adds support for the
gt9897 IC, which is a Berlin-A revision part.
The differences between revision D and A are rather minor, a handful of
address changes and a slightly larger read buffer. They were taken from
the driver published by Goodix, which does a few more things that don't
appear to be necessary for the touchscreen to work properly.

Some register groups reserve a byte at the end of their continuous
address space. Depending on the variant of silicon, this field may
share the same memory space as the lower byte of the system status
register (0x10).
In these cases, caching the reserved byte and writing it later may
effectively reset the device depending on what happened in between
the read and write operations.
Solve this problem by avoiding any access to this last byte within
offending register groups. This method replaces a workaround which
attempted to write the reserved byte with up-to-date contents, but
left a small window in which updates by the device could have been
clobbered.
Now that the driver does not touch these reserved bytes, the order
in which the device's registers are written no longer matters, and
they can be written in their natural order. The new method is also
much more generic, and can be more easily extended to new variants
of silicon with different register maps.
As part of this change, the register read and write functions must
be gently updated to support byte access instead of word access.

Some older Clevo barebones have problems like no or laggy keyboard after
resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.
We could not activly retest these devices because we no longer have them in
our archive, but based on the other old Clevo barebones we tested where the
new quirk had the same or a better behaviour I think it would be good to
apply it on these too.

Some older Clevo barebones have problems like no or laggy keyboard after
resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.
While the old quirk combination did not show negative effects on these
devices specifically, the new quirk works just as well and seems more
stable in general.

Some older Clevo barebones have problems like no or laggy keyboard after
resume or boot which can be fixed with the SERIO_QUIRK_FORCENORESTORE
quirk.
The PB71RD keyboard is sometimes laggy after resume and the PC70DR, PB51RF,
P640RE, and PCX0DX_GN20 keyboard is sometimes unresponsive after resume.
This quirk fixes that.

The delay is specified in a device property, so the duration can be

Matrix keypads with high capacity need a longer settle time after
enabling all columns before re-enabling interrupts. The delay gives
the system time to settle and avoids spurious interrupts.
Add a new optional device property to configure the delay after
enabling all columns. The default is no delay.

TECNO Pocket Go is a kickstarter handheld by manufacturer TECNO Mobile.
It poses a unique feature: it does not have a display. Instead, the
handheld is essentially a pc in a controller. As customary, it has an
xpad endpoint, a keyboard endpoint, and a vendor endpoint for its
vendor software.

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.
Since the vb2_ops_wait_prepare/finish callbacks already rely on that field,
we can safely drop these callbacks.
This simplifies the code and this is a step towards the goal of deleting
these callbacks.
