ASoC: rt5682s: Fix the wrong jack type detected

Commit Message

From: Derek Fang <[e-mail]>

Some powers were changed during the jack insert detection and clk's
enable/disable in CCF.
If in parallel, the influence has a chance to detect the wrong jack
type.

We refer to the below commit of the variant codec (rt5682) to fix
this issue.
  ASoC: rt5682: Fix deadlock on resume

1. Remove rt5682s_headset_detect in rt5682s_jd_check_handler and
   use jack_detect_work instead of.
2. Use dapm mutex used in CCF to protect most of jack_detect_work.

Thanks!

[1/1] ASoC: rt5682s: Fix the wrong jack type detected
      commit: c07ac3ee76e5e5506bca9c03fbbb15e40ab28430

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
