Karsten Graul 995433b795 net/smc: fix access to parent of an ib device ... The parent of an ib device is used to retrieve the PCI device attributes. It turns out that there are possible cases when an ib device has no parent set in the device structure, which may lead to page faults when trying to access this memory. Fix that by checking the parent pointer and consolidate the pci device specific processing in a new function.
