Subject: [PATCH] ASoC: SOF: Intel: hda-dai: Drop misleading comment regarding dma_data
Git-commit: 402355e6cdbebf15f2c40cd9469b924c97b94b32
Patch-mainline: v6.0-rc1
References: jsc#PED-850
The comment in hda_link_dma_hw_params() is no longer valid as the dma_data
is set to NULL at system suspend as well.
Instead of rewording the comment to state the obvious: try to take the
hext_stream from the dma_data and if it is not set then assign a new one
and store it as dma_data.
