Since commit 498209445124 ("regulator: core: simplify return value on suported_voltage") regulator_is_supported_voltage() returns a real boolean, so errors make _opp_supported_by_regulators() return false. The VDD1/VDD2 regulators on twl4030 are neither defined with voltage lists nor with the continuous flag set, so regulator_is_supported_voltage() returns false and an error before above mentioned commit (which was considered success) The result is that after the above mentioned commit cpufreq does not work properly e.g. dm3730.
