Check for uart_ops structures that are only stored in the ops field of a uart_port structure. This field is declared const, so uart_ops structures that have this property can be declared as const also.
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 uart_ops i@p = { ... };
@ok@ identifier r.i; struct uart_port e; position p; @@ e.ops = &i@p;
@bad@ position p != {r.p,ok.p}; identifier r.i; struct uart_ops e; @@ e@i@p
@depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct uart_ops i = { ... }; // </smpl>
