The patch

ASoC: Intel: Skylake: Fix to use the actual size for TLV control

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: Dharageswari R dharageswari.r@intel.com Date: Fri, 8 Jul 2016 18:15:03 +0530 Subject: [PATCH] ASoC: Intel: Skylake: Fix to use the actual size for TLV control

DSP expects the actual length of parameters that is set through TLV to be passed in large config set, so pass the actual size received in tlv_control_set() instead of max size.
