Subject: Applied "regulator: anatop: set default voltage selector for pcie" to the regulator tree

The patch

   regulator: anatop: set default voltage selector for pcie

has been applied to the regulator tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git 

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: anatop: set default voltage selector for pcie

Set the initial voltage selector for vddpcie in case it's disabled
by default.

This fixes the below warning:
20c8000.anatop:regulator-vddpcie: Failed to read a valid default voltage selector.
anatop_regulator: probe of 20c8000.anatop:regulator-vddpcie failed with error -22
