Subject[ 054/150] ALSA: hda - Release assigned pin/cvt at error path of hdmi_pcm_open()
Date
3.8-stable review patch.  If anyone has any objections, please let me know.

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

From: Takashi Iwai <tiwai@suse.de>

commit 2ad779b7329d6894a80df94e693e72eaa0d56790 upstream.

If the driver detects and invalid ELD, it gives an open error.
But it forgot to release the assigned pin, converter and spdif ctls
before returning.
