When we try to recover a PCI function using echo 1 > /sys/bus/pci/devices/<id>/recover or manually with echo 1 > /sys/bus/pci/devices/<id>/remove echo 0 > /sys/bus/pci/slots/<slot>/power echo 1 > /sys/bus/pci/slots/<slot>/power clp_disable_fn() / clp_enable_fn() call clp_set_pci_fn() to first disable and then reenable the function. When the function is already in the requested state we may be left with an invalid function handle. To get a new valid handle we do a clp_list_pci() call. For this we need both the function ID and function handle in clp_set_pci_fn() so pass the zdev and get both. To simplify things also pull setting the refreshed function handle into clp_set_pci_fn() Signed-off-by:
