Hi,
this is a patch set for enhancement of HD-audio configuration. There are lots of cases where a quick is applied only with PCI or codec SSID matching but no corresponding model option entry is provided. In such a case, user had to modify and recompile the code, or using the early patching with patch option, both of which are cumbersome.
This option makes it easier to apply a quirk of another device. Now you can pass model option string in a form of 1234:abcd for specifying the SSID of the alias target.
