[PATCH] ASoC: rt5682s: Stabilize the combo jack detection
From: Derek Fang derek.fang@realtek.com
Changes: 1. Revise rt5682s_sar_power_mode and rt5682s_headset_detect to be more rational. 2. Manually set to the jack-unplugging state via rt5682s_headset_detect during going to suspend. Close unnecessary powers and prepare for re-detecting the CBJ during resuming. 3. Simplize rt5682s_resume.

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
