Freeing the gpio is a little on the iffy side since you actually care
about keeping the value. Perhaps you can change

This way we don't accidently reserve the vbus GPIO pin, but later on
defer the creation of our controller, because the phy device tree node
hasn't been probed yet.

Hi,
With current Linus' master tree my ibook started emitting a lot of annoying
csum calculation warnings. I've bisected it down to the commit seen in the
subject line, but I suppose the real problem lies somewhere a lot deeper and
only gets revealed thanks to the more clever checksum logic
goes back to relying on
TIF_NEED_RESCHED.
Boot tested on x86_64 and compile tested on ppc64.
