The patch

   regulator: bd718x7: Simplify the code by removing struct bd718xx_pmic_inits

has been applied to the regulator tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.6

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: bd718x7: Simplify the code by removing struct
 bd718xx_pmic_inits

Nowdays ROHM_CHIP_TYPE_AMOUNT includes not only BD71837/BD71847 but also
BD70528/BD71828 which are not supported by this driver. So it seems not
necessay to have pmic_regulators[ROHM_CHIP_TYPE_AMOUNT] as mapping table.
Simplify the code by removing struct bd718xx_pmic_inits and
pmic_regulators[ROHM_CHIP_TYPE_AMOUNT].
