The patch
ASoC: Intel: skl-hda-dsp-generic: use snd-hda-codec-hdmi
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
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: Kai Vehmanen kai.vehmanen@linux.intel.com Date: Tue, 29 Oct 2019 15:40:11 +0200 Subject: [PATCH] ASoC: Intel: skl-hda-dsp-generic: use snd-hda-codec-hdmi
Add support for using snd-hda-codec-hdmi driver for HDMI/DP instead of ASoC hdac-hdmi. This is aligned with how other HDA codecs are already handled.
When snd-hda-codec-hdmi is used, the PCM device numbers are parsed from card topology and passed to the codec driver. This needs to be done at runtime as topology changes may affect PCM device allocation.
