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/)
// <smpl> @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 = { ... }; // </smpl>
