regulator: Remove MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros 2011-05-27T09:49:10+00:00 Axel Lin axel.lin@gmail.com 2011-05-16T10:20:34+00:00 ecb9c4f5956afa2ca0a20a1f99932b9ff81de854 In current implementation, the original macro implementation assumes the caller pass the parameter starting from 1 (to match the register names in datasheet). Thus we have unneeded plus one then minus one operations when using MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros.
