[PATCH 0/3] Media Device Allocator API

[Shuah Khan]

Media Device Allocator API to allows multiple drivers share a media device.
Using this API, drivers can allocate a media device with the shared struct
device as the key. Once the media device is allocated by a driver, other
drivers can get a reference to it. The media device is released when all
the references are released.

This patch series has been tested with au0828 and snd-usb-audio drivers.
snd-usb-audio patch isn't included in this series. Once this patch series
is reviews and gets a stable state, I will send out the snd-usb-audio
patch.
