This should not be a problem because there's no ifdef else and
in that case the functions would be there.
In general, the way to avoid problems like this is to make all
code under drivers arch independent and pass the platform data
from arch specific code.
In this case the ASoC platform data should be passed from
arch/arm/*omap*/ board-*.c files to make the drivers generic.
We are going to get rid of cpu_is_omapxxxx macros in the drivers,
so please consider this when patching the ASoC drivers.
Anyways, Paul's patch should be merged during the -rc cycle
because it is currently blocking Amstrad delta being built:
