Hi Mauro,

your patch doesn't solve the problem, because saa7146_dma_free() doesn't stop a running
dma transfer of the saa7146. Since last weekend, I'm using the attached patch. I'm not
sure, if the functionality of video_end() must be split. Maybe the last part of
video_end() must be execute at the end of vidioc_streamoff().
