[PATCH 02/10] regulator: lm363x: Let core handle GPIO descriptor

From: Linus Walleij
Date: Wed Nov 28 2018 - 05:44:06 EST


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

Fixes: b2d751b7f69b ("regulator: lm363x: Pass descriptor instead of GPIO number")
