Subject: [PATCH 1/2] ALSA: hda - Expose codec type sysfs
Date: Mon, 13 Apr 2015 13:22:36 +0200	[thread overview]
Message-ID: <1428924157-6288-1-git-send-email-tiwai@suse.de> (raw)

The type field of HD-audio codec object should be exposed to
user-space so that it can identify which driver type to bind (legacy /
asoc).
