2017-01-31regulator: act8945a-regulator: constify regulator_ops structureBhumika Goyal1-1/+1
Declare regulator_ops structure as const as it is only stored in the ops field of a regulator_desc structure. This field is of type const, so regulator_ops structures having this property can be made const too.
