Subject: [PATCH] UBUNTU sound/pci/hda/: Don't probe invalid codecs (hda_intel.c)

Status: Committed in upstream alsa-kernel hg

From Takashi Iwai:

Fix the max number of codecs detected by HD-intel (and compatible)
controllers to 3. Some hardware reports extra bits as if
connected, and the driver gets confused to probe unexisting codecs.
