Ok I can provide a backport.
pci_dev_is_added() was added in

44bda4b7d26e9 PCI: Fix is_added/is_busmaster race condition

It looks to me like we can just replace the call with "dev-is_added" but I'll have to test this.

Indeed, the first patch alone fixes the original problem, the second only fixes a racing deadlock that could happen when /sys/bus/pci/devices/<dev>/recover (which previously didn't work) collides with /sys/bus/pci/slots/<slot>/power.
This should be quite hard to hit but nevertheless I'd like this to get fixed as well.

"dev->is_added" of course.
