From e8a33aa0e3bc22134bf2bf3ca6339d6a1b7ffe16 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 6 Dec 2018 13:43:39 +0100 Subject: [PATCH] regulator: lm363x: Let core handle GPIO descriptor Use the gpiod_get() rather than the devm_* version so that the regulator core can handle the lifecycle of these descriptors.
