These i2c_algorithm structures are only stored in the alg field of an i2c_adapter structure, which is declared as const. This declare the structures as const as well. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct i2c_algorithm i@p = { ... }; @ok@ identifier r.i;
