5.15-stable review patch. If anyone has any objections, please let me know.

commit f8367a74aebf88dc8b58a0db6a6c90b4cb8fc9d3 upstream.
errcmd_enable_error_reporting() uses pci_{read,write}_config_word() that return PCIBIOS_* codes. The return code is then returned all the way into the probe function igen6_probe() that returns it as is. The probe functions, however, should return normal errnos.
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal errno before returning it from errcmd_enable_error_reporting().
