A copy-paste error was introduced when bitmasks were converted to
macros, incorrectly setting the enable bitmask for ELDO2 to the one
for ELDO1 for the AXP22x units.
Fix it by using the correct macro.
On affected boards, ELDO1 and/or ELDO2 are used to power the camera,
which is currently unsupported.
Fixes: db4a555f7c4c ("regulator: axp20x: use defines for masks")

(Originally sent before v5.5-rc1 was tagged.)
Small fix. Patches [1] supporting the camera sensor interface on the
Allwinner R40 based BPI-M2U board depend on this at runtime to power on
the camera correctly.

The patch
regulator: axp20x: Fix AXP22x ELDO2 regulator enable bitmask
has been applied to the regulator tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-5.5
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
