    tty: serial: constify uart_ops structures · 069a47e5
    Julia Lawall authored
    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
