[PATCH] USB: SN9C10x driver updates
SN9C10x driver updates.
Changes: + new, - removed, * cleanup, @ bugfix
@ Fix stream_interrupt()
@ Fix vidioc_enum_input() and split vidioc_gs_input()
@ Need usb_get|put_dev() when disconnecting, if the device is open
* Use wait_event_interruptible_timeout() instead of wait_event_interruptible()
when waiting for video frames
* replace wake_up_interruptible(&wait_stream) with wake_up(&wait_stream)
* Cleanups and updates in the documentation
+ Use per-device sensor structures
+ Add support for PAS202BCA image sensors
+ Add frame_timeout module parameter
