Subject: [PATCH] ASoC: amd: acp: store xfer_resolution of the stream
Git-commit: c8786ac7bb374276b1c2b545b4a6be3b230be7cb
Patch-mainline: v6.6-rc1
References: bsc#1219136

Store the 'xfer_resolution' of the stream in private data structure,
it will be used to reprogram the xfer_resolution for the active stream
during system level resume.
