According to
$ git grep -n -A1 "return.*;" drivers/pci
there's at least one more instance in
drivers/pci/controller/dwc/pcie-designware-plat.c.

Not related to your patch, but I'm not really a fan of the block here
(needed because of the local "u32 val" declaration) because we end up
with two close braces at the same indent level. I'd rather declare
the variable at the top with the other local variables and dispense
with the braces.
