d9d87d90cc treewide: rename GPIO set callbacks back to their original names 
The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

722332f58a gpio: ljca: use new line value setter callbacks 
struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

3396995f9f gpio: ljca: Initialize num before accessing item in ljca_gpio_config 
With the new __counted_by annocation in ljca_gpio_packet, the "num"
struct member must be set before accessing the "item" array. Failing to
do so will trigger a runtime warning when enabling CONFIG_UBSAN_BOUNDS
and CONFIG_FORTIFY_SOURCE.

cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

476f18c089 gpio: ljca: use devm_mutex_init() to simplify the error path and remove() 
Destroying the mutexes is done at the end of remove() so switching to
devres does not constitute a functional change. Use devm_mutex_init()
and remove repetitions of mutex_destroy().
