You are right. I missed it and will send a revision.

I've also noticed some drivers doing non-standard stuff.
e.g.
- ehci-ps3.c and ohci-pst set .shutdown as well as .remove to to ps3_ehci_remove
- ehci-tilegx.c and ohci-tilegx call .remove in the .shutdown path
- ehci-mv.c checks for (!hcd->rh_registered) in the shudown & remove patch.
Is this necessary?

cheers,
