Now that alsa code is part of the driver, it can be compiled
only if alsa is enabled.

CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_V4L2=m
CONFIG_VIDEO_USBTV=y

Reverse-engineered driver for cheapo video digitizer, made from observations of
Windows XP driver. The protocol is not yet completely understood, so far we
don't provide any controls, only support a single format out of three and don't
support the audio device.
