[PATCH 04/10] regulator: max8952: Let core handle GPIO descriptor

From: Linus Walleij
Date: Wed Nov 28 2018 - 05:44:08 EST


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

Fixes: d7a261c2d1f2 ("regulator: max8952: Pass descriptor instead of GPIO number")
