Subject: linux-next: build failure after merge of the final tree (sound tree
 related)

Hi all,

After merging the final tree, today's linux-next build (i386 defconfig)
failed like this:

sound/pci/hda/patch_via.c:185:28: error: field 'loopback' has incomplete type
sound/pci/hda/patch_via.c:187:22: error: array type has incomplete element type

Caused by commit ada509ec00e4 ("ALSA: hda - Simplify analog-low-current
mode check for VIA codecs") which removed the CONFIG_SND_HDA_POWER_SAVE
protection of the usage, but not the definition in
sound/pci/hda/hda_local.h.

I have added the below patch for today:

From: Stephen Rothwell <sfr@...b.auug.org.au>
Date: Tue, 28 Jun 2011 16:46:09 +1000
Subject: [PATCH] ALSA: hda - remove SND_HDA_POWER_SAVE protection of struct
 hda_loopback_check

to fix build problems when it is disabled.
