From: Derek Fang <derek.fang@realtek.com>
When the system suspends, the codec driver will set SAR to
power saving mode if a headset is plugged in.
There is a chance to generate an unexpected IRQ, and leads to
issues after resuming such as noise from OMTP type headsets.

From: Derek Fang <derek.fang@realtek.com>
Sometimes, end-users change the jack type under suspending,
so it needs to re-detect the combo jack type after resuming to
avoid any unexpected behaviors.

[1/2] ASoC: rt5682: Avoid the unexpected IRQ event during going to suspend
commit: a3774a2a6544a7a4a85186e768afc07044aa507f
[2/2] ASoC: rt5682: Re-detect the combo jack after resuming
commit: 2cd9b0ef82d936623d789bb3fbb6fcf52c500367
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
