    Subject[PATCH 5.1 295/371] media: coda: Remove unbalanced and unneeded mutex unlock
    Date
    From: Ezequiel Garcia <ezequiel@collabora.com>

    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.
