[1/1] ASoC: amd: acp: modify config flag read logic commit: 8527ecc6cf25417a1940f91eb91fca0c69a5c553 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

Modify acp config flag read logic from ACP v7.0 onwards. Instead of reading from DMI table match entry, read the config flag value from BIOS ACPI table. This will remove updating DMI table when new platform support is added. Use FLAG_AMD_LEGACY_ONLY_DMIC flag as default one.
