From 6192b115c58b725789cb333b4e043a6491c8d313 Mon Sep 17 00:00:00 2001 From: Anson Huang Date: Thu, 17 May 2018 15:27:22 +0800 Subject: [PATCH] regulator: pfuze100: add .is_enable() for pfuze100_swb_regulator_ops [ Upstream commit 0b01fd3d40fe6402e5fa3b491ef23109feb1aaa5 ] If is_enabled() is not defined, regulator core will assume this regulator is already enabled, then it can NOT be really enabled after disabled. Based on Li Jun's patch from the NXP kernel tree.
