This loooks OK and I'm actually applying SPI patches so I could apply it
but I'm not sure I see the relevance of this patch to the rest of the
series (which is about ASoC).  Is there some reason why it's included in
this patch series or can it be applied to the SPI tree?  The SMDKs use
I2C for their CODEC control rather than SPI.

Also is there a binding document update or device tree file update to go
with this?

I appreciate that this is cut'n'paste from the code you're refactoring
but please don't split error messages over lines, it makes it hard to
grep for them in the kernel source.
