The patch
ASoC: soc-dai: fix DAI startup/shutdown sequence
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: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com Date: Mon, 30 Mar 2020 11:06:02 -0500 Subject: [PATCH] ASoC: soc-dai: fix DAI startup/shutdown sequence MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit
The addition of a single flag to track the DAI status prevents the DAI startup sequence from being called on capture if the DAI is already used for playback.
Fix by extending the existing code with one flag per direction.
