Subject: [PATCH 0483/1795] media: v4l: sh_mobile_ceu: Return buffers on
streamoff()
videobuf2 core reports an error when not all buffers have been returned
to the framework:
drivers/media/v4l2-core/videobuf2-core.c:1651
WARN_ON(atomic_read(&q->owned_by_drv_count))
Fix this returning all buffers currently in capture queue.
