From 265489003c463f3d78d622fba60d56d16b3009dd Mon Sep 17 00:00:00 2001 From: Daniel Walker Date: Mon, 5 Oct 2009 13:31:45 -0700 Subject: [PATCH] omap: iovmm: Add missing mutex_unlock I was using Coccinelle with the mutex_unlock semantic patch, and it unconvered this problem. It appears to be a valid missing unlock issue. This change should correct it by moving the unlock below the label. This patch is against the mainline kernel.
