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.

Subject: [PATCH] ASoC: rsnd: rsnd_ssi_can_output_clk() macro

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.
