Subject: kbuild: sparse needs CF not CHECKFLAGS

Documentation/sparse.txt tells to use:

    make C=2 CHECKFLAGS="-D__CHECK_ENDIAN__"

However, this still doesn't enable endian checks. The correct syntax is:

    make C=2 CF="-D__CHECK_ENDIAN__"

This documentation bug was introduced by the following commit:

    commit 1c7bafe7206d928eaccbcbd08d868733e0fb7054
    Author: Robert P. J. Day <rpjday@mindspring.com>
    Date:   Wed Sep 13 07:57:50 2006 -0400

	kbuild: clarify "make C=" build option

	Clarify the use of "make C=" in the top-level Makefile, and fix a
	typo in the Documentation file.

	Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

This `typo' was not a typo, as `CF' had been introduced much earlier, by:

    commit 7b49bb9aff8b14d15da58111d8908c877c0a525e
    Author: viro@ZenIV.linux.org.uk <viro@ZenIV.linux.org.uk>
    Date:   Fri Sep 9 21:14:35 2005 +0100

	[PATCH] kbuild: CF=<arguments> passes arguments to sparse

	Allows to add to sparse arguments without mutilating makefiles - just
	pass CF=<arguments> and they will be added to CHECKFLAGS.

Subject: ALSA: Allow to force model to intel-mac-v3 in snd_hda_intel
 (sigmatel).

Currently, even if you pass model=intel-mac-v3 as a module parameter to
snd_hda_intel, the function patch_stac922x (patch_sigmatel.c) will still
try to auto-detect the model type. This is a problem on my MacBook Pro 1st
generation, which needs intel-mac-v3, but sometimes incorrectly reports
0x00000100 as subsystem id, which causes the switch in patch_stac922x to
select intel-mac-v4.

To fix this, I added a new model called intel-mac-auto, so in case no
module parameter is passed, and an Intel Mac board is detected, the
model will be automatically detected, while no detection will be done
if the model is forced to intel-mac-v3.

This problem has been around for quite a while, and I used to fix it
by moving the case statement for 0x00000100 in patch_stac922x so that
intel-mac-v3 is chosen.

Another way to fix the problem would be to check if a module parameter
was set directly in patch_stac922x, using something like this:
if (spec->board_config == STAC_INTEL_MAC_V3 &&
	!codec->bus->modelname) {

But I think it is less elegant (if you prefer that way, I can prepare a
patch).
