Yeah since it is needed for at least the Exynos5420 Peach Pit and
Exynos5800 Peach Pi Chromebooks that use this PMIC.

I already posted an incremental patch [0] and Krzysztof is pushing it
through Kukjin for 4.3 [1].

I guess that's OK and there is no need to add it as a fix for the 4.2
-rc cycle since this is not really a regression. I mean, the max77802
regulator driver was never enabled for multi_v7_defconfig before.
