Oy... can you avoid the pointer dance by using
of_fdt_is_compatible()
from my recent set of patches?
I would like to get rid of the pointer dance. Is your patch set
going to make it
into .37? I didn't see any acks.
Obviously I meant .38 :-)
I'd like it too, but that's up to Grant.
Grant any guidance here?
I imagine some of the
bottleneck is that I don't have
an easy way to test on powerpc or microblaze at the moment, so it's not
clear that the code doesn't
break anything.
