The patch
ASoC: Intel: consistent HDMI codec probing code
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6
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

Multiple Intel ASoC machine drivers repeat the same pattern in their .late_probe() methods: they first check whether the common HDMI codec driver is used, if not, they proceed by linking the legacy HDMI driver to each HDMI port. While doing that they use some inconsistent code:
1. after the loop they check, whether the list contained at least one element and if not, they return an error. However, the earlier code to use the common HDMI driver uses the first element of the same list without checking. To fix this we move the check to the top of the function.
2. some of those .late_probe() implementations execute code, only needed for the common HDMI driver, before checking, whether the driver is used. Move the code to after the check.
3. Some of those functions also perform a redundant initialisation of the "err" variable.
This patch fixes those issues.
