This field is declared const, so i2c_algorithm structures that have this property can be declared as const also. This issue was identified using Coccinelle and the following semantic patch: @r disable optional_qualifier@ identifier i; position p; @@ static struct i2c_algorithm i@p = { ... }; @ok@ identifier r.i; struct i2c_adapter e; position p; @@ e.algo = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct i2c_algorithm i = { ... }; Signed-off-by: Gustavo A.
