* i2c: busses: constify i2c_algorithm structuresBhumika Goyal2017-02-09
| | | | | | | | | | | | | | Declare i2c_algorithm structures as const as they are only stored in the algo field of an i2c_adapter structure. This field is of type const, so i2c_algorithm structures having this property can be made const too.
