Subject[PATCH] pinctrl: lochnagar: select GPIOLIB
In a rare randconfig build I came across one configuration that does
not enable CONFIG_GPIOLIB, which is needed by lochnagar:

ERROR: "devm_gpiochip_add_data" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!
ERROR: "gpiochip_generic_free" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!
ERROR: "gpiochip_generic_request" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!
ERROR: "gpiochip_get_data" [drivers/pinctrl/cirrus/pinctrl-lochnagar.ko] undefined!

Add another 'select' like all other pinctrl drivers have.

Fixes: 0548448b719a ("pinctrl: lochnagar: Add support for the Cirrus Logic Lochnagar")

I wonder if GPIOLIB should just become mandatory when enabling the pinctrl
subsystem, or if there are still good reasons for leaving it disabled
on any machine that uses CONFIG_PINCTRL.
