Use set_jack ops to set jack for new machine drivers. Meanwhile, the old machine drivers can still call previous export function "nau8825_enable_jack_detect".

This looks like a separate change to support disabling jack detect which should be in a separate commit.
return 0;- } /* Ground HP Outputs[1:0], needed for headset auto detection
Should really be a blank line here.

I will separate it from this patch.

One other thing, sorry - your signoff should generally come last. If Mac wrote this then the commit should say it comes from them, if you worked on it together then Co-developed-by is usually used.

Thanks for your suggestion.

[1/2] ASoC: nau8825: add set_jack coponment support commit: c6167e10e76fb97d37613004046e66027b3a569b [2/2] ASoC: nau8825: add clock management for power saving commit: 6133148ca08a097ed8c57d7f5a7826723273049b
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
