ASoC: SOF: Intel: hda-stream: clear hstream->running flag in hw_params

ujfalusi · ujfalusi · commit 6603c7b2d4b0 · 2026-03-05T10:22:41.000+02:00
During hw_params call we make sure that the host DMA is stopped but the
hstream-&gt;running flag is not explicitly cleared at the same time.

If the host DMA fails to stop during previous use then the flag is left
set and on next start the host DMA will be left disabled since the
trigger:STOP will skip the DMA enable.
