SubjectApplied "regulator: provide regulator_bulk_set_supply_names()" to the regulator tree
Date
The patch

regulator: provide regulator_bulk_set_supply_names()

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: provide regulator_bulk_set_supply_names()

There are many regulator consumers who - before using the regulator
bulk functions - set the supply names in regulator_bulk_data using
a for loop.

Let's provide a simple helper in the consumer API that allows users
to do the same with a single function call.
