This code accidentally returns PTR_ERR(NULL) which is success.  It
should return a negative error code.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-linus

Thanks!

[1/1] regulator: max20086: fix error code in max20086_parse_regulators_dt()
      commit: 879cf8006475642b747aaaa4d06f7044ab2de794

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
