Subject: [media] omap3isp: Cancel all queued buffers when stopping the video stream Author: Laurent Pinchart <[email protected]> Date: Sun Apr 20 20:59:03 2014 -0300 When stopping a video stream the driver waits for ongoing DMA opeations to complete for the currently active buffer, but doesn't release the non-active queued buffers. This isn't a problem in most cases as the video device is usually closed after the stream is stopped, which will release all the buffers. However the problem would generate a warning when switching to videobuf2. Fix it by cancelling all buffers after DMA operations have completed.
