Subject: Applied "regulator: add regulator_get_linear_step() stub helper" to the regulator tree

The patch

   regulator: add regulator_get_linear_step() stub helper

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: add regulator_get_linear_step() stub helper

The regulator header has empty inline functions for most interfaces,
but not regulator_get_linear_step(), which has just grown a user
that does not depend on regulators otherwise:

drivers/clk/tegra/clk-tegra124-dfll-fcpu.c: In function 'get_alignment_from_regulator':
drivers/clk/tegra/clk-tegra124-dfll-fcpu.c:555:19: error: implicit declaration of function 'regulator_get_linear_step'; did you mean 'regulator_get_drvdata'? [-Werror=implicit-function-declaration]
  align->step_uv = regulator_get_linear_step(reg);
                   ^~~~~~~~~~~~~~~~~~~~~~~~~
                   regulator_get_drvdata
cc1: all warnings being treated as errors
scripts/Makefile.build:278: recipe for target 'drivers/clk/tegra/clk-tegra124-dfll-fcpu.o' failed

Add the missing stub along the others.
