    Subject[PATCH 4.8 23/85] ALSA: hda - ignore the assoc and seq when comparing pin configurations
    Date
    4.8-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Hui Wang <hui.wang@canonical.com>

    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.
