      [media] [1/2,ver,1.89] DM04/QQBOX Interupt Urb and Timing changes · 95c21c41
      tvboxspy authored 
      Reduce buffer size of Interupt urb to 128 bytes and polling
interval to 8.

The devices buffer appears to only handle a maxium of 40 bytes.
If the buffer is full a slowing effect is noticed causing occasionnal
dropped streaming packets.

For uvc device, dev->vdev.dev is the &intf->dev,
uvc_delete code is as below:
	usb_put_intf(dev->intf);
	usb_put_dev(dev->udev);

	uvc_status_cleanup(dev);
	uvc_ctrl_cleanup_device(dev);

	if (dev->vdev.dev)
		v4l2_device_unregister(&dev->vdev);

Fix it by get_device in v4l2_device_register and put_device in v4l2_device_disconnect

      The Cinergy Hybrid cards are known not to need an artificial delay after
USB accesses so the quirk can safely be enabled.

      Thierry Reding authored 
      Some devices support fast access to registers using the USB interface
while others require a certain delay after each operation. This commit
adds a quirk that can be enabled by devices that don't need the delay.

      [media] mt9t001: Aptina (Micron) MT9T001 3MP sensor driver · 0a54b86a
      Laurent Pinchart authored 
      The MT9T001 is a parallel 3MP sensor from Aptina (formerly Micron)
controlled through I2C.

The driver creates a V4L2 subdevice. It currently supports binning and
cropping, and the gain, exposure, test pattern and black level controls.

      [media] omap3isp: video: Avoid crashes when pipeline set stream operation fails · 5b6c3ef0
      Laurent Pinchart authored 
      If streaming can't be enabled on the pipeline, the DMA buffers queue is
not emptied. If the buffers then get freed the queue will end up
referencing free memory. This is usually not an issue, as the DMA queue
will be reinitialized the next time streaming is enabled, before
enabling the hardware.

However, if the sensor connected at the pipeline input is free-running,
the CCDC will start generating interrupts as soon as it gets powered up,
before the streaming gets enabled on the hardware. This will make the
CCDC interrupt handler access freed memory, causing a crash.

Reinitialize the DMA buffers queue in isp_video_streamon() if the error
path to make sure this situation won't happen.
