[PATCH 0/5] fix SIU and Migo-R sound for 2.6.37

[Guennadi Liakhovetski]

Conversion to the multi-component design has broken the SIU driver and its 
users. This patch series fixes the breakages. All patches against 
next/master, but one of them (#4) shall also go into 2.6.36.

Thanks

[PATCH 1/5] ASoC: fix compile breakage of the sh/siu driver

[Guennadi Liakhovetski]

The sh/siu ASoC driver doesn't compile because of a function defined static in
the source and extern in a header. Remove the unneeded declaration in the
header.

Better yet would be to rename this to wm8978 (and adjust the board).

Well, what does "better" mean? That it's your suggestion or your 
requirement for this patch to be accepted? I grepped codecs/ and have 
found enough of both versions, so, maybe we can take it like this and then 
decide upon a unified naming?

I mean I've already done a version that renames everything to wm8978.  I
don't like the other users for I2C devices terribly much either and will
post patches for at least the drivers I'm responsible for soon.

Fwiw, the reason for the "-codec" suffix was to distinguish codec
devices from their other multi-function IC siblings. It also makes sense
here to use convention with the device naming too (even if the device is
single purpose).

Yes, MFDs do need something to distinguish them.

I don't find it adds much more than making the name longer to type - we
always use the name in a context where it's fairly obvious that the
device is a CODEC.

Please don't do this.  If you want a patch to go to Linus send it
separately.  If you do feel the need to include the patch in another
series not for Linus for some reason then please include it at the start
of the series so that it can be easily split out.

Ok, sorry, but in fact this patch and the rest of the series are 
independent, so, it should be no problem just to pick it up from here, or 
do I have to re-send anything?

I've not yet tried applying it but I'd anticipate some breakage trying
to do so due to the multi-component changes in the file in for-2.6.37.
I'll do so later today or tomorrow, if it applies fine there's no need
to resubmit.

I did, worked fine - only with offsets. Otherwise, I certainly wouldn't 
suggest to take it directly.
