The patch
ASoC: rt5651: Fix bias_level confusion
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

From: Hans de Goede hdegoede@redhat.com Date: Sun, 25 Feb 2018 11:46:49 +0100 Subject: [PATCH] ASoC: rt5651: Fix bias_level confusion
The rt5651_set_bias_level() function was turning everything off at SND_SOC_BIAS_STANDBY, rather then at SND_SOC_BIAS_OFF, requiring the bias- level to be raised to SND_SOC_BIAS_PREPARE before turning anything on.
This is not how the bias-levels are supposed to work, this commit fixes this by turning everything off at the SND_SOC_BIAS_OFF level and enabling the pwr-bits needed for minimum functionality at SND_SOC_BIAS_STANDBY.
This fixes the minimum set of pwr-bits not getting enabled when force-enabling some dapm-supplies (e.g. for jack type detection), which raises the bias-level to standby.
