No, that is the right solution. And I have no idea how the patch can solve it. You are really driving me crazy. I already explained to you how device is enumerated, the patch CAN NOT FIX ANYTHING.

You have Alder Lake-P that re-uses Tiger Lake pin control IP. So, what's the problem (except documentation)? The resolution of this bug is correct, i.e. RESOLVED INVALID.

It seems that official specifications are confidential, but in any case, search for these documents.

I don't believe that patch solves anything. Check the `lsmod` output and other things, but it's impossible that this patch solves the problem. And again, it makes really wrong, there are no such pins in Alder Lake-N/S supported platforms.
