The patch
ASoC: rsnd: rsnd_ssi_can_output_clk() macro
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.

For example SSI0/SSI1 case, SSI1 can share pin with SSI0. And then, SSI1 needs SSI0's clock. This clock controlling is very picky and difficult to understand in current code.
This patch adds new rsnd_ssi_can_output_clk() macro, the code will be more understandable.
