commit 6aaad58c87 upstream.
The driver uses atomic version of gpiod_set_value() without any real
reason. It is called in a workqueue under mutex so it could sleep
there. Changing it to "can_sleep" flavor allows to use the driver with
all GPIO chips.

In case of error, the function devm_gpiod_get() returns ERR_PTR() and
never returns NULL. The NULL test in the return value check should be
replaced with IS_ERR().
