Looking at the code I think this commit is simply broken for

I'll revert the patch.
Ugh, sorry about missing that too. Ack to a revert - thinking about
those PPC symptoms, it might actually be that other architectures could
also get into the same pickle just by unbinding and rebinding a driver
(e.g. switching to VFIO then back again).
