The patch
ASoC: hdac_hdmi: Handle MST pin jack detection at boot/resume
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

The ELD notification can be received asynchronously from the graphics side and this may happen just at the moment the sound driver is initializing and notification will be missed. Similarly at system resume, the notification is ignored as the ELD and connection states are updated in anyway at the end of the resume. So check the jack status in boot/resume by querying the port presence based on pin caps and report the jack status.
