From b264a70eef880aff31652a10ffee9c03e949b69b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 23 Sep 2013 19:14:31 +0100 Subject: [PATCH] mfd: mc13xxx: Don't require lock for simple register I/O Since the conversion to regmap there has been no need for device level locking for I/O as regmap provides locking so remove the locks.
