When we plug a 3-ring headset on the Dell machine (VID: 0x10ec0255, SID: 0x1028067e), the headset mic can't be detected, after apply this patch, the headset mic can work well.

Thanks, applied.
But now I'm slowly thinking of cleaning these messes; can't we detect this a bit more elegantly?
I've been thinking of that too. I'm wondering if the combination of vendor (Dell), codec (e g ALC255), and pin config could be wise here? I e, if all of the pin configuration default values are exactly the same, then we should be reasonably sure that it is to be used in the same way.
So, essentially have a quirk table with PCI Subvendor + codec + pin config as key? What do you think of that?
