The patch
ASoC: rt5677: keep analog power register at SND_SOC_BIAS_OFF
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
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: Ben Zhang benzh@chromium.org Date: Fri, 6 Sep 2019 12:46:24 -0700 Subject: [PATCH] ASoC: rt5677: keep analog power register at SND_SOC_BIAS_OFF
Instead of clearing RT5677_PWR_ANLG2 (MX-64h) to 0 at SND_SOC_BIAS_OFF, we only clear the RT5677_PWR_CORE bit which is set at SND_SOC_BIAS_PREPARE. MICBIAS control bits are left unchanged.
This fixed the bug where if MICBIAS1 widget is forced on, MICBIAS control bits will be cleared at suspend and never turned back on again, since DAPM thinks the widget is always on.
