[1/1] ASoC: soc-pcm.c: Clear DAIs parameters after stream_active is updated commit: 1da681e52853f0abfbfff8c69833d31e538ff9c0 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

DAIs parameters should be cleared if there's no active stream. Before, we implemented it in soc_pcm_hw_free() by detecting stream_active. If the running stream is the last active stream, we're going to clear parameters. However it will cause DAIs parameters never be cleared if there're more than one stream. For example, we have stream1 and stream2 about to stop. stream2 executes soc_pcm_hw_free() before stream1 executes soc_pcm_close(). At the moment, stream2 should clear DAIs parameters. Since stream_active is not yet updated by stream1 in soc_pcm_close(), stream2 will not clear DAIs parameters. In result both stream1 and stream2 don't clear the parameters. This patch moves DAIs parameters cleanup after stream_active is updated.
