From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>
commit b2ebcf42a48f4560862bb811f3268767d17ebdcd upstream.
Free widgets for static pipelines in sof_tear_down_pipelines(). But this feature is unavailable in older firmware with ABI < 3.19. Just reset widget use_count's for this case. This would ensure that the secondary cores enabled required for topology setup are powered down properly before the primary core is powered off during system suspend.
