This is prepare patch for switching s5m8767 regulator driver to
use GPIO descriptor. DTS for exynos5250 spring incorrectly specifies
"active low" polarity for the DVS and DS line. But per datasheet,
they are actually active high. So add polarity quirk for it.

[2/2] regulator: s5m8767: Convert to GPIO descriptors
      commit: 16b19bfd80402bb98135c4b65344e859883766ec

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
