PCI: Improve __pci_read_base() robustness Local variables 'l' and 'sz' are uninitialized. Normally, they would be initialized by pci_read_config_dword() but when an error occurs, some drivers immediately return an error code, which leaves the argument uninitialized. Provide a safe initial value to make the code more robust. Signed-off-by: Marc Gonzalez <marc_gonzalez@sigmadesigns.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
