From f44b07472f29ae313ce875dc7b9c75b100c608b8 Mon Sep 17 00:00:00 2001 From: Pascal Paillet Date: Wed, 13 Nov 2019 11:27:37 +0100 Subject: [PATCH] regulator: core: Let boot-on regulators be powered off [ Upstream commit 089b3f61ecfc43ca4ea26d595e1d31ead6de3f7b ] Boot-on regulators are always kept on because their use_count value is now incremented at boot time and never cleaned. Only increment count value for alway-on regulators. regulator_late_cleanup() is now able to power off boot-on regulators when unused.
