[PATCH 0/2] ASoC: SOF: Extend the enabled DSP core handling

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

Hi,

In the current code, we enable a widget core when it is set up and
disable it when it is freed. This is problematic with IPC4 because
widget free is essentially a NOP and all widgets are freed in the
firmware when the pipeline is deleted. This results in a crash during
pipeline deletion when one of it's widgets is scheduled to run on a
secondary core and is powered off when widget is freed. So, change the
logic to enable all cores needed by all the modules in a pipeline when
the pipeline widget is set up and disable them after the pipeline
widget is freed.

Regards,
Peter
