Subject: Applied "regulator: giving regulator controlling gpios a non-empty label when used through the devicetree." to the regulator tree

The patch

   regulator: giving regulator controlling gpios a non-empty label when used through the devicetree.

has been applied to the regulator tree at

   https://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: giving regulator controlling gpios a non-empty
 label when used through the devicetree.

When the label is empty, it causes missing information and limits diagnostics
for instances such as 'cat /sys/kernel/debug/gpio'

Setting the label to the regulator supply_name will point to the device
using the gpio(s).
