No, just pointing out that there would be a way to avoid the ifdef 
without messing up driver behaviour. I'm fine with the ifdef - not least 
because it clearly eliminates code that would be unreachable.

(On second thought - I don't want to speculate whether there's weird 
compiler options that could result in the nvram_check_checksum and 
nvram_read_bytes symbols to still be referenced in the final link, even 
though IS_BUILTIN(CONFIG_NVRAM) always evaluates to false. Best leave 
this as-is.)

Of course - I'd seen Geert's acked-by on some of the patches and forgot 
to check which still required acks.

Cheers,
