[1/1] ASoC: simple-card-utils: Don't reset clock of active DAI commit: 5bbe2918acccfa60de1c1a2139de9cc5441d5796 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

Playback or capture errors are seen when clock is reset during an active stage of DAI. Presently this scenario happens when DAI has both playback and capture sessions running and one of these finishes first which will be followed by clock rate reset. The remaining active session will be affected in such case. Address this problem by allowing clock rate reset to happen only when the DAI is no more active.
