This is initial support for the Asus MyCinema U3100Mini Plus. The driver
in its current form gets detected and loads properly.
Scanning using dvbscan works without problems, Locking onto a channel
using tzap also works fine. Only playback using tzap -r + mplayer was
tested and was fully functional.
It uses the af9035 USB Bridge chip, with an af9033 demodulator. The tuner
used is the FCI FC2580.

1) We always re-create the input-urb on resume, so we must also always

2) If we're going to do an init_transfer, then that will destroy the urb

once the stream is started. So there is little use in creating it, if

In commit a3d6e8cc0e gspca_dev->dev is set
to NULL on disconnect, before calling stop0. The plan was to get rid of
gspca_dev->present and instead simply check for gspca_dev->dev everywhere
where we were checking for present. This should be race free since all users
of gspca_dev->dev hold the usb_lock, or so I thought.
But I was wrong, drivers which use a work-queue + synchronous bulk transfers
to get the video data don't hold the usb_lock while doing so, their stop0
callbacks stop the workqueue, so they won't be using gspca_dev->dev anymore
after the stop0 call, but they might be dereferincing it before, so we should
not set gspca_dev->dev to NULL on disconnect before calling stop0.
This also means that the workqueue functions in these drivers cannot
use gspca_dev->dev to check if they need to stop because of disconnection,
so we will need to keep gspca_dev->present around, and set that to 0 on
disconnect, before calling stop0. Unfortunately as part of the plan to remove
gspca_dev->present, these workqueues where already moved over to checking
for gspca_dev->dev instead of gspca_dev->present as part of commit
254902b01d, so this patch also reverts those
parts of that commit.

That simplifies the life for users, as they can just keep
