Subject: Applied "regulator: rn5t618: fix rc5t619 ldo10 enable" to the regulator tree

The patch

   regulator: rn5t618: fix rc5t619 ldo10 enable

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.4

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

Subject: [PATCH] regulator: rn5t618: fix rc5t619 ldo10 enable

LDO9 and LDO10 were listed with the same enable bits.
That looks insane and there are no provisions in the code for handling such
a special case. Also other out-of-tree drivers use a separate bit to
enable it.
Example:
https://github.com/brunotl/kernel-kobo-mx6sl-ntx/blob/master/drivers/regulator/ricoh619-regulator.c
So it seems to be clearly a bug.
I cannot fully check it on my board without schematics and just discovered
this during code analysis for another problem.
