Subject: [PATCH] ASoC: SOF/soundwire: re-add substream in params_stream structure
Git-commit: 1d905d355ef329d2e4fbe04569dea7cb041419c1
Patch-mainline: v6.5-rc1
References: jsc#PED-6045 jsc#PED-6036 jsc#PED-6104 jsc#PED-6114 jsc#PED-6067 jsc#PED-6123

An earlier simplification to only pass the direction is no longer
suitable, all the ACE2.x HDaudio DMA management relies on access to
the substream structure.

This patch is an iso-functionality change, the HDaudio DMA parts will
be provided separately.
