[alsa-devel] [PATCH] ALSA: hda: ignore assoc when comparing pin configurations

[Kai-Heng Feng]

Commit [64047d7f4912 ALSA: hda - ignore the assoc and seq when comparing
pin configurations] may still fail to match pins on some machines,
because the bitmask it used only ignore seq but not assoc.
Change the bitmask to also ignore assoc.

Thanks to Hui Wang for the analysis.
