Subject: ALSA: hda - Release assigned pin/cvt at error path of hdmi_pcm_open()
From: Takashi Iwai <[email protected]>
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.
