From 402355e6cdbebf15f2c40cd9469b924c97b94b32 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 12 Jul 2022 16:16:19 +0300 Subject: ASoC: SOF: Intel: hda-dai: Drop misleading comment regarding dma_data The comment in hda_link_dma_hw_params() is no longer valid as the dma_data is set to NULL at system suspend as well.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.
