Check for snd_soc_ops structures that are only stored in the ops field of a snd_soc_dai_link structure. This field is declared const, so snd_soc_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 snd_soc_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_dai_link e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i, e; position p; @@ struct snd_soc_dai_link e[] = { ..., { .ops = &i@p, }, ..., }; @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_soc_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_soc_ops i = { ... }; // </smpl> The effect on the layout of the .o files is shown by the following output of the size command, first before then after the transformation: text data bss dec hex filename 5027 2488 416 7931 1efb sound/soc/rockchip/rk3399_gru_sound.o 5219 2312 416 7947 1f0b sound/soc/rockchip/rk3399_gru_sound.o text data bss dec hex filename 3499 1648 384 5531 159b sound/soc/rockchip/rockchip_max98090.o 3563 1584 384 5531 159b sound/soc/rockchip/rockchip_max98090.o text data bss dec hex filename 3455 1536 384 5375 14ff sound/soc/rockchip/rockchip_rt5645.o 3519 1480 384 5383 1507 sound/soc/rockchip/rockchip_rt5645.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org> |
