Subject: Applied "regulator: tps65917/palmas: Simplify multiple dereference of pdata->reg_init[idx]" to the regulator tree

The patch

   regulator: tps65917/palmas: Simplify multiple dereference of pdata->reg_init[idx]

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: tps65917/palmas: Simplify multiple dereference of
 pdata->reg_init[idx]

Converting dt to platform data logic involves picking up information
that is unique per regulator, however we can improve readability of
the code by allocating and referencing pdata->reg_init[idx] once in
the loop.

While at it, use sizeof(*pointer) when allocating pointer. This allows
for structure name changes with minimal code change.
