      drm/sun4i: constify component_ops structures · dfeb693d
      Julia Lawall authored
      These component_ops structures are only used as the second argument to
      component_add and component_del, which are declared as const, so the
      structures can be declared as const as well.
      
      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 component_ops i@p = { ... };
      
      @ok1@
      identifier r.i;
      expression e1;
      position p;
      @@
      
      component_add(e1,&i@p)
      
      @ok2@
      identifier r.i;
      expression e1;
      position p;
      @@
      
      component_del(e1, &i@p)
      
      @bad@
      position p != {r.p,ok1.p,ok2.p};
      identifier r.i;
      struct component_ops e;
      @@
      
      e@i@p
      
      @depends on !bad disable optional_qualifier@
      identifier r.i;
      @@
      
      static
      +const
       struct component_ops i = { ... };
      // </smpl>
      
      The result of the size command before the change is (arm):
      
         text       data         bss     dec      hex filename
         5266        236           8    5510     1586 sun4i_backend.o
         6393        236           8    6637     19ed sun4i_tcon.o
         3700        368           8    4076      fec sun4i_tv.o
         1668        108           0    1776      6f0 sun6i_drc.o
      
      and after the change:
      
         text       data         bss     dec     hex filename
         5274        228           8    5510    1586 sun4i_backend.o
