parent[media] cx88: add missing alloc_ctx support (diff)
[media] cx88: remove leftover start_video_dma() call
The start_streaming op is responsible for starting the video dma, so it shouldn't be called anymore from the buf_queue op. Unfortunately, this call to start_video_dma() was added to the start_streaming op, but was forgotten to be removed from the buf_queue op, which is where it used to be before the vb2 conversion. Calling this function twice causes very hard to find errors: sometimes it works, sometimes it doesn't. It took me a whole friggin' day to track this down, and in the end it was just luck that my eye suddenly triggered on that line.
