Subject: ALSA: hda - ignore the assoc and seq when comparing pin configurations

From: Hui Wang <[email protected]>

commit 64047d7f4912de1769d1bf0d34c6322494b13779 upstream.

More and more pin configurations have been adding to the pin quirk table, lots of them are only different from assoc and seq, but they all apply to the same QUIRK_FIXUP, if we don't compare assoc and seq when matching pin configurations, it will greatly reduce the pin quirk table size.

We have tested this change on a couple of Dell laptops, it worked well.
