[PATCH 1/2] ASoC: nau8825: add set_jack coponment support

[David Lin]

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.

Should really be a blank line here.

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!

[1/2] ASoC: nau8825: add set_jack coponment support

      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
