Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next Thanks! [1/1] ASoC: fsl_ssi: Fix TDM slot setup for I2S mode commit: 9fd914d917da05641b42cab7d40bdf8ab06dac3b 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

When using the driver in I2S TDM mode, the _fsl_ssi_set_dai_fmt() function rewrites the number of slots previously set by the fsl_ssi_set_dai_tdm_slot() function to 2 by default. To fix this, let's use the saved slot count value or, if TDM is not used and the slot count is not set, proceed as before.
