[PATCH 1/2] leds: Drop duplicate LEDS_EXPRESSWIRE config

[Duje Mihanović]

While moving said config symbol out of the "if NEW_LEDS" block, I
accidentally left a copy inside that block. Remove it.

[PATCH 2/2] backlight: ktd2801: Depend on GPIOLIB

[Duje Mihanović]

The LEDS_EXPRESSWIRE library used by the driver requires GPIOLIB. Make
sure this dependency is not left unsatisfied.
