Subject: ASoC: wm_adsp: Ensure DSP controls are always persistent
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=65d17a9ce9f24a3aaf7d614251fdcc1b2121765f;p=deliverable%2Flinux.git

ASoC: wm_adsp: Ensure DSP controls are always persistent

Currently DSP controls are persistent (across DSP On/Off) only
if they were set whilst the DSP is off. This change makes the
controls persistent irrespective of when they are set.
