ALSA: hda - Fix regression of HDMI codec probing
Browse files Browse the repository at this point in the history
The commit c4bfe94 causes a regression on some codecs at probing.
Since this was just a workaround to shut up a kernel warning, it'd be
better to revert and fix properly.  So we ended up with re-adding the
cleanup callback.
