Merge tag 'regulator-fix-v4.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator fixes from Mark Brown: "Three changes here: two run of the mill driver specific fixes and a change from Mark Rutland which reverts some new device specific ACPI binding code which was added during the merge window as there are concerns about this sending the wrong signal about usage of regulators in ACPI systems" * tag 'regulator-fix-v4.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: regulator: fixed: Revert support for ACPI interface regulator: axp20x: AXP806: Fix dcdcb being set instead of dcdce regulator: twl6030: fix range comparison, allowing vsel = 59
