[alsa-devel] [PATCH] V2, Convert bitfields in ASOC into full int width

The fix was trivial enough so I've made and applied it (and done some brief testing of my own) - please be more careful in future.

I did that making checkpatch happy. I don't have easily buildable test cases for powerpc so I'm doing this via inspection. I'll see if I can mess with Kconfig and force all of the codecs to build.
So this one is ok with the \ added? Next round I need to clean everything up to make it 32 bit safe instead of only 16 bit. It will probably touch some of the same code and needs to apply on top of this patch.

Check the upstream branch of:
git://opensource.wolfsonicro.com/linux-2.6-asoc
which contains a patch that does just that.

Yes. Like I say, I've applied it.
