[alsa-devel] [PATCH] ASoC: Intel: Atom: fix regression on compress DAI

[Pierre-Louis Bossart]

Commit a1068045883ed4a18363a4ebad0c3d55e473b716 added a
dependency on the compress-cpu-dai channel_min field
which was removed earlier by commit
77095796ae9cbaf315f80611edb5aa569796e339 as part of the
baytrail cleanups.

The net result was a regression at probe on all Atom platforms
with no sound card created.

Fix by adding explicit initialization for channel_min to 1
for the compress-cpu-dai.
