[PATCH 5.1 295/371] media: coda: Remove unbalanced and unneeded mutex unlock

[Greg Kroah-Hartman]

From: Ezequiel Garcia <ezequiel@xxxxxxxxxxxxx>

commit 766b9b168f6c75c350dd87c3e0bc6a9b322f0013 upstream.

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.
