The patch ASoC: rsnd: ssi: wait maximum 5ms for status check 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 3fd391fb7c97ab6dfb9e44926a265566d1d1ab79 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Mon, 16 Apr 2018 00:38:13 +0000 Subject: [PATCH] ASoC: rsnd: ssi: wait maximum 5ms for status check It is waiting udelay(50) x 1024 (= 50ms) for status check in worst case, but it is overkill. And we shouldn't use udelay() for 50us (linux/Documentation/timers/timers-howto.txt) Waiting maximum udelay(5) x 1024 (= 5ms) is very enough for status check. This patch fixes these issue.
