The patch
ASoC: Intel: Skylake: add LARGE_CONFIG_GET IPC support
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

From: Mousami Jana mousami.janax@intel.com Date: Thu, 3 Dec 2015 23:29:55 +0530 Subject: [PATCH] ASoC: Intel: Skylake: add LARGE_CONFIG_GET IPC support
For messages which have larger payload than mailbox data, we need to split the payload using set of messages containing mailbox size as payload.
For sending such payload we already support LARGE_CONFIG_SET IPCs and now to query such payload add LARGE_CONFIG_GET IPC
