The patch
ASoc: rsnd: dma: Calculate dma address with consider of BUSIF
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.
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.

From: Jiada Wang jiada_wang@mentor.com Date: Mon, 3 Sep 2018 07:07:43 +0000 Subject: [PATCH] ASoc: rsnd: dma: Calculate dma address with consider of BUSIF
DMA address calculated by rsnd_dma_addr() only considers BUSIF0 so far. But BUSIF1 ~ BUSIF7 also maybe used, in the future.
This patch updates DMA address calculations, to also consider BUSIF number used by SSI.
One note is that we can't support SSI9-4/5/6/7 so far, because its address is out of calculation rule.
