Mauro,
Please pull this changeset which implements a basic ALSA interface for
the ivtv driver.
The changes are a modified cut and paste from cx18 and cx18-alsa. It
inherets all the problems of the cx18-alsa driver: locking
inconsistencies, ALSA mixer interface is not enabled, hardcoded sample
rate of 48 ksps regardless of the real audio sample rate, etc. However
in testing, it works well enough for userspace to get basic FM radio and
TV audio via ALSA.
Regards,
Andy
