From 78f2c50bb4e1884318542cc5f674afb106555273 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 29 Aug 2016 10:12:01 -0300 Subject: [PATCH] [media] constify i2c_algorithm structures 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/) // @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.alg = &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 = { ... };
