The patch ASoC: AMD: Send correct channel for configuring DMA descriptors has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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 >From fa9d2f17c23fb3ea6b659b1bfe4ca10551a19e56 Mon Sep 17 00:00:00 2001 From: "Agrawal, Akshu" <Akshu.Agrawal@xxxxxxx> Date: Mon, 16 Jul 2018 15:02:40 +0800 Subject: [PATCH] ASoC: AMD: Send correct channel for configuring DMA descriptors Earlier, ch1 was used to define ACP-SYSMEM transfer and ch2 for ACP-I2S transfer. With recent patches ch1 is used to define channel order number 1 and ch2 as channel order number 2.
