[alsa-devel] [PATCH 7/9] ASoC: Intel: Skylake: Fix to check return value of dsp init

[Vinod Koul]

From: Jeeja KP <jeeja.kp at intel.com>

If DSP initialization fails, ipc to disable notification
will cause NULL ptr exception as ipc is not initialized.
This patch returns error if dsp init fails before
sending disable notification ipc.
