Subject: [PATCH] media: i2c: ov5647: use our own mutex for the ctrl lock

__v4l2_ctrl_handler_setup() and __v4l2_ctrl_modify_range() contains an assertion to verify that the v4l2_ctrl_handler::lock is held, as it should only be called when the lock has already been acquired. Therefore use our own mutex for the ctrl lock, otherwise a warning will be reported.
