Message-ID: <1451406723-32040-1-git-send-email-ckeepax@opensource.wolfsonmicro.com> Date: Tue, 29 Dec 2015 16:32:03 +0000 From: Charles Keepax <ckeepax@...nsource.wolfsonmicro.com> To: <cw00.choi@...sung.com> CC: <myungjoo.ham@...sung.com>, <linux-kernel@...r.kernel.org>, <patches@...nsource.wolfsonmicro.com> Subject: [PATCH] extcon: arizona: Use DAPM mutex helper functions We should be using the helper functions to lock the DAPM mutex not accessing it directly. There are no ill effects of this as the moment but it is best practice, and the implementation could be changed in the future.
