[PATCH] regulator: fixed: Let core handle GPIO descriptor

From: Linus Walleij
Date: Thu Dec 06 2018 - 07:43:38 EST


Use the gpiod_get() rather than the devm_* version so that the
regulator core can handle the lifecycle of these descriptors.

Fixes: efdfeb079cc3 ("regulator: fixed: Convert to use GPIO descriptor only")
