Mauro Carvalho Chehab 5cbe9f3acf [media] ivtv: fix two smatch warnings
Smatch currently produces two warnings:
	drivers/media/pci/ivtv/ivtv-fileops.c:901 ivtv_v4l2_close() warn: suspicious bitop condition
	drivers/media/pci/ivtv/ivtv-fileops.c:1026 ivtv_open() warn: suspicious bitop condition

Those are false positives, but it is not hard to get rid of them by
using a different way to evaluate the macro, splitting the logical
boolean evaluation from the bitmap one.

Embed the video_device struct to simplify the error handling and in
order to (eventually) get rid of video_device_alloc/release.

Andy Walls 4313902ebe [media] ivtv-alsa, ivtv: Connect ivtv PCM capture stream to ivtv-alsa interface driver
This change hooks up the ivtv PCM capture stream to the ivtv-alsa interface
driver.  This is all that should be needed for basic CX23415/CX23416 PCM
audio capture to be available via ALSA device nodes.

Andy Walls 269c11fbac [media] ivtv, ivtv-alsa: Add initial ivtv-alsa interface driver for ivtv
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.
