[PATCH 1/2] ASoC: Intel: Skylake: Don't use dma I2S config structure in kernel

[jeeja.kp]

From: GuruprasadX Pawse <guruprasadx.pawse@intel.com>

I2S blob config structure can change between DSP copier module versions.
We are not modifying these structures anyway and NHLT blobs specify them
properly, so use the blob directly to send the dma_control ipc instead
of using the predefined I2S blob config structure.

Applied "ASoC: Intel: Skylake: Removed the unused I2S blob structure" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: Skylake: Removed the unused I2S blob structure

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.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
