Commit a551d91473 (ALSA: hda - Use regmap for command verb caches, too) breaks TOSLINK

[Markus Trippelsdorf]

Hi,

since commit a551d914:
Author: Takashi Iwai <tiwai@xxxxxxx>
Date:   Thu Feb 26 12:34:49 2015 +0100

    ALSA: hda - Use regmap for command verb caches, too

my DAC receives no signal over TOSLINK-S/PDIF anymore.

Reverting the commit on top of the current Linus tree "fixes" the issue.
