Merge series "Add support for on demand pipeline setup/destroy" from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

Browse Source 
Hi,

The previous, v2 of this series was sent by Daniel Baluta:
https://lore.kernel.org/alsa-devel/20210917143659.401102-1-daniel.baluta@oss.nxp.com/

We have agreed that it might be better that someone from Intel is going to take it
from here as we already have the infrastructure up to test and verify the
dynamic pipelines support.

Changes since v2 (sent by Daniel Baluta):
- patch 10: Fix NULL point dereference in hda_dai_update_config()
- I have kept Daniel's SoB for the series.

Changes since v1:
- Signed-off-by tag added by Daniel

This series implements initial support for dynamic pipelines to setup/teardown
pipeline as needed when a PCM is open/closed.

Initially dynamic pipelines are only supported with single core setup which will
be expanded with a follow-up series.

Review with SOF community at
https://github.com/thesofproject/linux/pull/2794

The feature has been merged on 1st of April to sof-dev, all issues found since
has been fixed and squashed to this upstream series.

Regards,
Peter
