The patch
ASoC: intel: initialize return value properly
has been applied to the asoc tree at
https://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

When CONFIG_SND_SOC_HDAC_HDMI is disabled, we can run into an uninitialized variable:
sound/soc/intel/skylake/skl.c: In function 'skl_resume': sound/soc/intel/skylake/skl.c:326:6: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
I have run into this on today's linux-next kernel, but it appears that this is an older problem that was just hard to trigger with randconfig builds as CONFIG_SND_SOC_HDAC_HDMI would in effect be impossible to disable when having SND_SOC_INTEL_SKYLAKE enabled.
