The patch ASoC: audio-graph-scu-card: tidyup "prefix" parsing 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 2624fc7882244abeb4dabbd5b67328676a109b6a Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Thu, 22 Nov 2018 00:56:21 +0000 Subject: [PATCH] ASoC: audio-graph-scu-card: tidyup "prefix" parsing audio-graph-scu-card.c is supporting "prefix" which is used to avoid DAI naming conflict when CPU/Codec matching. But, sound card might have multi sub-devices, and each codec might need each prefix. Now, ASoC is supporting snd_soc_of_parse_node_prefix(), let's support it on audio-graph-scu-card, too. It is keeping existing DT style. It can't support each codec's prefix if sound card had multi sub-devices without this patch.
