[Mark Brown]

The patch

   ASoC: rsnd: ssi: Fix issue in dma data address assignment

has been applied to the asoc tree at

   https://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: ssi: Fix issue in dma data address assignment

Same SSI device may be used in different dai links,
by only having one dma struct in rsnd_ssi, after the first
instance's dma config be initilized, the following instances
can no longer configure dma, this causes issue, when their
dma data address are different from the first instance.
