I thought about this, too. I just wondered how many drivers would actually need
a 'pdata'-preparation routine before probe, and if this would not cause too
much overhead for those who don't. But as you say OF might not the only case
where this is needed, then it might be a reasonable choice to have an extra
call fot setting up pdata. Then again, if we have preparation routines for
OF,UEFI,... for each and every driver, uh, the bloat :(

I might have a try :)
