Then better to split the patch to two, one just for disabling the dead
ext mic pin, and another for adding the headset mic chain. The former
can go to stable while the latter goes to next together with the
previous ALC269_FIXUP_HEADSET_MIC patch.

If adding a new fixup entry for stable, put to somewhere in the middle
so that git cherry-pick would work. Appending to the tail is
problematic because of a few previous fixups aren't merged to stable,
thus the new entry cannot be applied cleanly.

thanks,
