[alsa-devel] [PATCH V2 07/10] ASoC: Intel: Skylake: Disable notifications at boot after DSP FW init

[jeeja.kp at intel.com]

From: G Kranthi <gudishax.kranthikumar at intel.com>

DSP firmware sends notification every 1ms, which is disabled in runtime
suspend. But if a system has no runtime pm, we keep getting
notification, so disable after FW init as well.
