3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 30ebc5e44d057a1619ad63fe32c8c1670c37c4b8 upstream.
We recently introduced a new return -ENODEV in this function but we need
to unlock before returning.
[mchehab@xxxxxxxxxx: found two patches with the same fix. Merged SOB's/acks into one patch]
