Subject: 3.0.11 backport 11b8fc6ae54bf18a48c94e181c37ca135b858b42 is broken, please revert

Hi,

I noticed that audio stopped working after 3.0.10 which I narrowed down to:

11b8fc6ae54bf18a48c94e181c37ca135b858b42 mfd: Fix twl4030 dependencies for audio codec

The commit message has this bit:

"In commit 57fe7251f5bfc4332f24479376de48a1e8ca6211
the CONFIG_TWL4030_CODEC was renamed
into CONFIG_MFD_TWL4030_AUDIO, thatswhy the codec
was not detected."

Which is this one: http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=commit;h=57fe7251f5bfc4332f24479376de48a1e8ca6211

Let's look at the top commit:

koen@...inion:/OE/tentacle/build/tmp-angstrom_2010_x-eglibc/work/beagleboard-angstrom-linux-gnueabi/linux-3.0.12-r113a/git/drivers/mfd$ git show 8509e14

So the commit that is referenced is not actually in 3.0.x! Long story short:

git revert 11b8fc6ae54bf18a48c94e181c37ca135b858b42 is broken ; make ; scp uImage beagleboard

root@...gleboard:~# cat /proc/asound/cards 
0 [omap3beagle    ]:  - omap3beagle
                     omap3beagle

So please revert  11b8fc6ae54bf18a48c94e181c37ca135b858b42 for 3.0.13, cherrypicking the TWL codec rename is a world of hurt since it needs other fixes to get pulled in as well.

regards,

Koen
