Subject: Applied "regulator: wm8400: Get rid of wm8400_block_read/wm8400_set_bits functions" to the regulator tree

The patch

   regulator: wm8400: Get rid of wm8400_block_read/wm8400_set_bits functions

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: wm8400: Get rid of
 wm8400_block_read/wm8400_set_bits functions

The only user of wm8400_block_read/wm8400_set_bits functions is the
wm8400 regulator driver. At the context of all the callers, we can
use regmap_bulk_read/regmap_update_bits directly.
Thus remove wm8400_block_read/wm8400_set_bits functions.
