Subject: [PATCH RESEND1 00/12] ALSA: vsnd: Add Xen para-virtualized frontend driver

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@...m.com>

This patch series adds support for Xen [1] para-virtualized
sound frontend driver. It implements the protocol from
include/xen/interface/io/sndif.h with the following limitations:
- mute/unmute is not supported
- get/set volume is not supported
Volume control is not supported for the reason that most of the
use-cases (at the moment) are based on scenarious where
unprivileged OS (e.g. Android, AGL etc) use software mixers.

Both capture and playback are supported.

Thank you,
Oleksandr

Resending because of rebase onto [2] + added missing patch
