From deb78bd24e0cd196acffbedffb9bed7a8839b227 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Thu, 2 May 2019 18:00:43 -0400 Subject: [PATCH] media: coda: Remove unbalanced and unneeded mutex unlock 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.
