For example, there are over 10 entries in the pintbl for: 0x10ec0255, 0x1028, "Dell", ALC255_FIXUP_DELL1_MIC_NO_PRESENCE If we define a new tbl like below, and with the new adding match function, we can remove those over 10 entries: SND_HDA_PIN_QUIRK(0x10ec0255, 0x1028, "Dell", ALC255_FIXUP_DELL1_MIC_NO_PRESENCE, {0x19, 0x40000000}, {0x1a, 0x40000000},), Here we put 0x19 and 0x1a in the tbl just because these two pins are undefined on Dell laptops with the codec alc255, and these two pins will be overwritten by ALC255_FIXUP_DELL1_MIC_NO_PRESENCE. In summary: the new match will check vendor id and codec id first, then check the pin_cfg defined in the tbl, only all pin_cfgs in the tbl are undef and the corresponding pin_cfgs on the laptop are undef too, this match returns true. This new match function has lower priority than existing match functions, so the existing tbls still work as before after applying this patch. My plan is to change the existing tbl to undef tbl for MIC_NO_PRESENCE fixups gradually.
