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: Jeeja KP jeeja.kp@intel.com Date: Tue, 27 Oct 2015 09:22:52 +0900 Subject: [PATCH] ASoC: Intel: Skylake: Add support for virtual dsp widgets
In SKL topology routes, some paths can be connected by a widget which are not a DSP FW widget and virtual with respect to firmware. In these case when module has to bind, then the virtual DSP modules needs to skipped till a actual DSP module is found which connects the pipelines.
So we need to walk the graph and find a widget which is real in nature. This patch adds that support and splits skl_tplg_pga_dapm_pre_pmu_event() fn with parsing code to skl_tplg_bind_sinks() fn and call that recursively as well as while parsing
The patch moves code a bit while splitting so diffstat doesn't tell real picture
