3.16.82-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Stephan Gerhold stephan@gerhold.net
commit 458ea3ad033fc86e291712ce50cbe60c3428cf30 upstream.
Those regulators are not actually supported by the AB8500 regulator driver. There is no ab8500_regulator_info for them and no entry in ab8505_regulator_match.
As such, they cannot be registered successfully, and looking them up in ab8505_regulator_match causes an out-of-bounds array read.
