On some platforms, the sy8827n enable gpio may also be used for other
purpose, so make it NONEXCLUSIVE to support this case.

Thanks!

[1/1] regulator: sy8827n: make enable gpio NONEXCLUSIVE
      commit: 5054740e0092aac528c0589251f612b3b41c9e7b

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

When you say "other purpose" which other purposes do you mean - another
regulator, or something else?

Yep, other regulators in my usage case.

As explained in the discussion about this flag: I hate this but I
haven't yet gotten around to proposing an alternative, so reluctantly:
