Fixed all the "errors" reported by checkpath.pl in ks7010_stio.c
The "TODO" file ask to take the 80 character limit lightly, so
the file still has some warnings about character limit. All the
errors have been removed.

Currently block plug holds up to 16 non-mergeable requests. This makes
sense if the request size is small, eg, reduce lock contention. But if
request size is big enough, we don't need to worry about lock
contention. Holding such request makes no sense and it lows the disk
utilization.
In
This is corresponding part for blk-mq. Disk with multiple hardware
queues doesn't need this as we only hold 1 request at most.

It does not matter if given GPIO may sleep or not when reading state,
polling is always done in a non-atomic context, so we should always
be able to simply use gpiod_get_value_cansleep().
Also let's note in the logs when we fail to read gpio state.

GPIO descriptors are the preferred way over legacy GPIO numbers
nowadays. Convert the driver to use GPIO descriptors internally but
still allow passing legacy GPIO numbers from platform data to support
existing platforms.

Commit 633a21d80b4a ("input: gpio_keys_polled: Add support for GPIO

is supposed to be part of platform data and not modifiable by the driver.
To keep the data constant, let's move the descriptor to

When devm_clk_get fails for core clock, the failure was ignored
and the core_clk was explicitly set to NULL so that other
remaining clocks can be queried. However, now that we have a
clean way of expressing the clock dependency, return failure when
devm_clk_get fails for core clock.
On earlier chiptsets (APQ8064, MSM8660, MSM8690, MSM8916,
APQ8084, MSM8974) crypto operations of TZ were depends on crypto
clocks controlled by users/clients. However on MSM8996 crypto clocks
control is handled internally in TZ itself. The current series of
patches handle this clock dependency in
