* [media] media: remove the setting of the flag V4L2_FL_USE_FH_PRIORamakrishnan Muthukrishnan2014-07-041-1/+0

* [media] vb2: stop_streaming should return voidHans Verkuil2014-04-231-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | The vb2 core ignores any return code from the stop_streaming op. And there really isn't anything it can do anyway in case of an error. So change the return type to void and update any drivers that implement it. The int return gave drivers the idea that this operation could actually fail, but that's really not the case. The pwc amd sdr-msi3101 drivers both had this construction: if (mutex_lock_interruptible(&s->v4l2_lock)) return -ERESTARTSYS; This has been updated to just call mutex_lock(). The stop_streaming op expects this to really stop streaming and I very much doubt this will work reliably if stop_streaming just returns without really stopping the DMA.

This seems to work fine for most existing devices. However, at least the SpeedLink VAD Laplace webcam has the video endpoint on interface number 3 (which fortunately doesn't cause any trouble because ist uses bulk transfers only).
