ALSA: hda: when comparing pin configurations, ignore assoc in addition to seq
commit 5e0ad0d8747f3e4803a9c3d96d64dd7332506d3c upstream. Commit [64047d7f4912 ALSA: hda - ignore the assoc and seq when comparing pin configurations] intented to ignore both seq and assoc at pin comparing, but it only ignored seq. So that commit may still fail to match pins on some machines. Change the bitmask to also ignore assoc. v2: Use macro to do bit masking. Thanks to Hui Wang for the analysis. Fixes: 64047d7f4912 ("ALSA: hda - ignore the assoc and seq when comparing...")
