Subject: [PATCH] media: coda: Remove unbalanced and unneeded mutex unlock
Git-commit: 766b9b168f6c75c350dd87c3e0bc6a9b322f0013
Patch-mainline: v5.3-rc1
References: bsc#1051510

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.
