[PATCH v3 0/5] gpiolib: of: quirk cleanups and TWL4030 external mute quirk

[Dmitry Torokhov]

This series contains minor cleanups to drivers/gpio/gpiolib-of.c and
adds a legacy property quirk for TWL4030.

Specifically, it removes a redundant IS_ENABLED() check in
of_find_mt2701_gpio(), compiles of_find_trigger_gpio() conditionally on
CONFIG_LEDS_TRIGGER_GPIO, adds a legacy property name quirk for the
TWL4030 codec external mute GPIO ("ti,hs_extmute_gpio"), cleans up
formatting in drivers/gpio/gpiolib-of.c to pass checkpatch, and uses
__free(device_node) in of_get_named_gpiod_flags().

Note that the companion fix for the TWL4030 codec driver itself (which
fixes looking up the GPIO on the "codec" child node) has been posted
separately [1] and has no build-time dependency on this series.
