There is a custom loop that repeats parts of gpiod_get_array_value_cansleep().
Use that in conjunction with bitmap API to make code shorter and easier to
follow.
With this done, add an upper check for amount of GPIOs given based on
the driver's code.

The ilitek touchscreen driver uses the non-sleeping gpiod_set_value
function for reset.
Switch to using gpiod_set_value_cansleep() when controlling reset_gpio to
support GPIO providers that may sleep, such as I2C GPIO expanders.
Further switch the mdelay calls on the reset path to fsleep (preferred
in non-atomic contexts).
This fixes noisy complaints in kernel log for gpio providers that do

Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistentcy cannot be addressed without refactoring the API.
alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.
This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.
This patch continues the effort to refactor worqueue APIs, which has begun
with the change introducing new workqueues and a new alloc_workqueue flag:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
This specific workload do not benefit from a per-cpu workqueue, so use
WQ_UNBOUND on the custom workqueue instead.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.
Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

Fix an uninitialised variable (key) in afs_alloc_anon_key() by setting it
to cell->anonymous_key. Without this change, the error check may return a
false failure with a bad error number.
Most of the time this is unlikely to happen because the first encounter
with afs_alloc_anon_key() will usually be from (auto)mount, for which all
subsequent operations must wait - apart from other (auto)mounts. Once the
call->anonymous_key is allocated, all further calls to afs_request_key()
will skip the call to afs_alloc_anon_key() for that cell.

Pull spi fixes from Mark Brown:
"A disappointingly large set of device specific fixes that have built
up since I've been a bit tardy with sending a pull requests as people
kept sending me new new fixes.
The bcm63xx and lpspi issues could lead to corruption so the fixes are
fairly important for the affected parts, the other issues should all
be relatively minor"
