From 63239e4bf7eff394d2bcba95999d6e3eae2be6a6 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 15 Oct 2018 11:02:40 +0200 Subject: regulator: Fetch enable gpiods nonexclusive Since the core regulator code is treating GPIO descriptors as nonexclusive, i.e. it assumes that the enable GPIO line may be shared with several regulators, let's add the flag introduced for fixing this problem on fixed regulators to all drivers fetching GPIO descriptors to avoid possible regressions.
