From 94b5c0288299c7b962a7e2cb734293b77b96cffe Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 18 Apr 2014 16:07:44 +0800 Subject: [PATCH] ARM: imx: lock is always valid for clk_gate2 The imx specific clk_gate2 always has a valid lock with the clock. So the validation on gate->lock is not really needed. Remove it.
