From e35b5ab0a706f3794d35652b557a5e6a4dde5391 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 11 Sep 2016 14:14:37 +0200 Subject: gpio: constify gpio_chip structures These structures are only used to copy into other structures, so declare them as const. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct gpio_chip i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct gpio_chip e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct gpio_chip i = { ... };
