PCI: ibmphp: Fix use-before-set in get_max_bus_speed()
The "rc" variable is only initialized on the error path. The caller doesn't check the return but, if "rc" is non-zero, then this function is basically a no-op. Fixes: 3749c51ac6c1 ("PCI: Make current and maximum bus speeds part of the PCI core") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
