[PATCH AUTOSEL 6.1 03/53] ASoC: SOF: pm: Always tear down pipelines before DSP suspend

[Sasha Levin]

From: Ranjani Sridharan <ranjani.sridharan at linux.intel.com>

[ Upstream commit d185e0689abc98ef55fb7a7d75aa0c48a0ed5838 ]

When the DSP is suspended while the firmware is in the crashed state, we
skip tearing down the pipelines. This means that the widget reference
counts will not get to reset to 0 before suspend. This will lead to
errors with resuming audio after system resume. To fix this, invoke the
tear_down_all_pipelines op before skipping to DSP suspend.
