3.16.82-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Seung-Woo Kim <sw0312.kim@xxxxxxxxxxx> commit 704c6c80fb471d1bb0ef0d61a94617d1d55743cd upstream. >From isp_video_release(), &isp->video_lock is held and subsequent vb2_fop_release() tries to lock vdev->lock which is same with the previous one. Replace vb2_fop_release() with _vb2_fop_release() to fix the recursive locking.
