[alsa-devel] [PATCH] ALSA: hda - Add missing terminating entry to SND_HDA_PIN_QUIRK macro

[David Henningsson]

Without this terminating entry, the pin matching would continue
across random memory until a zero or a non-matching entry was found.

The result being that in some cases, the pin quirk would not be
applied correctly.
