Re: [PATCH] devicetree: Add empty of_platform_populate() for !CONFIG_OF_ADDRESS (sparc)

["Cousson, Benoit" <b-cousson-l0cyMroinI0@public.gmane.org>]

Hi Grant,

In fact this patch is not working for build without CONFIG_OF like x86.

Because if CONFIG_OF_DEVICE is not defined, then the stub for 
of_platform_populate will not be defined either. It should exist for any 
config without CONFIG_OF.

Building twl4030 for x86 is actually broken.
