Subject: Applied "regulator: stpmic1: Add static const qualifier at peroper places" to the regulator tree
The patch
regulator: stpmic1: Add static const qualifier at peroper places
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: stpmic1: Add static const qualifier at peroper
places
The regulator_linear_range arrays and stpmic1_regulator_cfgs are only
accessed by this driver and the values are never changed so make them
static const. regulator_ops variables can also be const.
Also clean up a few empty lines in regulator_linear_range array.
