bcm4377_init_cfg() uses pci_{read,write}_config_dword() that return PCIBIOS_* codes. The return codes are returned into the calling bcm4377_probe() which directly returns the error which is of incorrect type (a probe should return normal errnos).
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal errno before returning it from bcm4377_init_cfg. This conversion is the easiest by adding a label next to return and doing the conversion there once rather than adding pcibios_err_to_errno() into every single return statement.
