    Subject: [PATCH 124/570] staging: Bulk convert the semaphore mess

    init_MUTEX(_LOCKED) and DECLARE_MUTEX are going away. Bulk convert
    staging users.

    Cc: Greg Kroah-Hartman <gregkh@suse.de>

    I have broken the original patch down into separate patches per file because theoriginal patch no longer applies.
