Subject: [ 23/46] media: rc: unlock on error in show_protocols()

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 30ebc5e44d057a1619ad63fe32c8c1670c37c4b8 upstream.

We recently introduced a new return -ENODEV in this function but we need
to unlock before returning.

[mchehab@...hat.com: found two patches with the same fix. Merged SOB's/acks into one patch]
