Argh! You're right, of course.
I didn't see it, because the only existing place where this check is
made is in the PCI glue layer. Pushing it into the HCDs themselves is
obviously the right thing to do.
Manjanuth, let's do this. You can write a preliminary patch that puts
this check at the end of the ohci_suspend() routine, and then resubmit
your series.
