The patch ASoC: audio-graph-scu-card: tidyup asoc_simple_card_parse_daifmt() timing 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 338d7159c488268dd4ccc6a69ab4af8f829f75d0 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Thu, 22 Nov 2018 00:57:09 +0000 Subject: [PATCH] ASoC: audio-graph-scu-card: tidyup asoc_simple_card_parse_daifmt() timing Current audio-graph-scu-card driver is parsing codec position for DPCM and consider DAI format. But, current operation is doing totally pointless, because 1) asoc_simple_card_parse_daifmt() will be called not only for 1st codec on current implementation, and it will be used as fixed format 2) it should be called for each CPU/Codec pair. Let's tidyup asoc_simple_card_parse_daifmt() timing.
