I sent this last week as part of my devres patches but it is purely a
bug fix and can be merged now.

On a slot_reset event pci_disable_device() is never called so calling
pci_enable_device() will unbalance the enable count.

ACK all the parts except s2io. Of course, I haven't seen the pci_reenable_device 
rename patch in Jeff's tree yet...

Actually, it is in Linus's tree on git.kernel.org.
