Hi Mike

You need to understand what is actually causing the problem. If it no
NVMEM, or no OF? The kernel config was part of the email, so you
should be able to reproduce the failure.

We don't normally add #ifdef in code. Instead we implement stub
functions in the header file, which would in this case return
something like -ENODEV.

Dave has already take this patch. So you need to do an incremental
fix.
