[PATCH v1] ASoC: amd: acp: Audio is not resuming after s0ix
From: Hemalatha Pinnamreddy hemalatha.pinnamreddy2@amd.com
Audio fails to resume after system exits suspend mode due to accessing incorrect ring buffer address during resume. This patch resolves issue by selecting correct address based on the ACP version.

[1/1] ASoC: amd: acp: Audio is not resuming after s0ix commit: 3ee257aba1d56c3f0f1028669a8ad0f1a477f05b
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
