From e9c142b0d2c08178a9e146d47d8fe397373bda3e Mon Sep 17 00:00:00 2001 From: Michał Mirosław Date: Mon, 10 Aug 2020 06:33:32 +0200 Subject: regulator: remove locking around regulator_notifier_call_chain() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit regulator_notifier_call_chain() doesn't need rdev lock and rdev's existence is assumed in the code anyway. Remove the locks from drivers.
