This is a cut-and-paste port of the cx18-alsa driver to create an ivtv-alsa interface module for the ivtv driver. It is not actually hooked-up to the PCM stream DMA buffers from the ivtv driver yet. That will be done in a coming change, since that portion is so very different from the cx18 driver. This code has all or more of the bugs and shortcomings of the cx18-alsa interface driver: inconsistent use of itvsc->slock, ivtv-alsa-mixer.c is dead code, assumes 48 ksps regardless of the actual setting of the audio capture, problems with proper struct ivtv and struct ivtv_stream housekeeping, struct ivtv_open_id.v4l2_fh abuse, and $DIETY knows what else.
