From daf22c3c4444e10a852a2f460f5cb1a43038bd53 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 28 Nov 2011 22:37:35 +0800 Subject: [PATCH] wm97xx_battery: Use DEFINE_MUTEX() for work_lock work_lock can be initialized automatically with DEFINE_MUTEX() rather than explicitly calling mutex_init(). This patch also removes an unused bat_lock mutex.
