The patch
ASoC: mxs-saif: check BUSY bit in hw_params() only if not mclk_in_use
has been applied to the asoc tree at
git://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

If something else, typically a codec, has enabled mclk, the BUSY bit may be set when hw_params() is called without this being an error. This check thus causes intermittent failures to configure the sound device when used in such a manner. Fix this by making the test conditional on !saif->mclk_in_use.
