The code change itself looks OK, so could you try to resubmit in a
proper format with sign-off?  The spaces in the patches got broken by
your mailer, and you might need to fix the mailer setup (at best
submit via git-send-email).  As a last resort, you can use an
attachment, too.

This should have been already addressed recently by the fix commit
0aacce7c32e4 ("ALSA: hda: Avoid quirk matching with zero PCI SSID").
Let me know if the issue still persists even with this fix.
