Subject: media: coda: Remove unbalanced and unneeded mutex unlock
Author: Ezequiel Garcia <ezequiel@xxxxxxxxxxxxx>
Date: Thu May 2 18:00:43 2019 -0400
The mutex unlock in the threaded interrupt handler is not paired
with any mutex lock. Remove it.
This bug has been here for a really long time, so it applies
to any stable repo.
