Subject: [PATCH] arm: omap: iovmm: add missing mutex_unlock
Date: Sat, 26 Sep 2009 14:37:19 -0700	[thread overview]
Message-ID: <1254001039-27976-1-git-send-email-dwalker@fifo99.com> (raw)

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.
