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 6401 228 8 6637 19ed sun4i_tcon.o 3708 360 8 4076 fec sun4i_tv.o 1676 100 0 1776 6f0 sun6i_drc.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1478971198-3659-1-git-send-email-Julia.Lawall@lip6.fr |
