[PATCH v3 0/2] media: uvcvideo: Code cleanup for dev->status

[Ricardo Ribalda <ribalda@chromium.org>]

There is no need to make a kzalloc just for 16 bytes. Let's embed the data
into the main data structure.

Now that we are at it, lets remove all the castings and open coding of
offsets for it.

[Christoph, do you think dma wise we are violating any non written rules? :) thanks]
