Subject: media: coda: Remove unbalanced and unneeded mutex unlock Author: Ezequiel Garcia ezequiel@collabora.com 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.
