The error checking code relative to the invocations of kinect_read() does not return the actual return code of the function just called, it returns "res" which still contains the value of the last invocation of a previous kinect_write(). Return the proper value, and while at it also report with -EREMOTEIO the case of a partial transfer. Reported-by:

sleep_on and its variants are broken and going away soon. This changes the omap vout driver to use wait_event_interruptible_timeout instead, which fixes potential race where the dma is complete before we schedule. [hans.verkuil@cisco.com: replaced interruptible_sleep_on_timeout by wait_event_interruptible_timeout in the commit msg, obvious typo] Signed-off-by:

interruptible_sleep_on is racy and going away. This replaces one use in the radio-cadet driver with a wait_event_interruptible call. Special care was taken that accesses to the rdsin and rdsout indices are always done with dev->lock held. Signed-off-by:

The check would check the pointer, which is never less than 0. According to the error message, the correct check would be to check the return value of ipipe_mode. Check that instead. Reported-by:

The queue_setup handler takes an optional format argument that can be used to allocate buffers for a format different than the current format. The uvcvideo driver doesn't support changing the format when buffers have been allocated, but there's no reason not to support allocating buffers larger than the minimum size. When the format argument isn't NULL verify that the requested image size is large enough for the current format and use it for the buffer size. Signed-off-by:

videobuf2 already ensures that the number of buffers will not exceed VIDEO_MAX_FRAME, which is equal to our arbitraty limit of UVC_MAX_VIDEO_BUFFERS. Remove the duplicate check. Signed-off-by:

Isochronous endpoints on devices with speed == USB_SPEED_WIRELESS can have a max packet size ranging from 1-3584 bytes. Add a case to uvc_endpoint_max_bpi to handle USB_SPEED_WIRELESS. Otherwise endpoints for those devices will fall to the default case which masks off any values > 2047. This causes uvc_init_video to underestimate the bandwidth available and fail to find a suitable alt setting for high bandwidth video streams. Signed-off-by:

Memory-to-memory pipelines have no external subdev, we shouldn't try to locate one and validate its configuration. The driver currently works by chance due to another bug that results in failure to locate the external subdev being ignored. This gets rid of the "omap3isp omap3isp: can't find source, failing now" error message in the kernel log when operating on a memory-to-memory pipeline. Signed-off-by:

Drop the vid_limit module option: there is really no need to limit this. No other driver does that. If you try to allocate more buffers then vb2 will automatically reduce the number of buffers anyway. Also add sanity checks if the size in the fmt argument is going to be used and drop the code that checks against *nbuffers == 0: this can never happen (the vb2 framework ensures that) and the code was wrong anyway since *nbuffers should have been set to the minimum number of required buffers which is 1 for this driver. Since vivi is often used as a template driver it is good to have this driver be as compliant as possible. This broken code was for example copied to the s2255 driver (which is being fixed as well).
