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 8748 1024 0 9772 262c sound/soc/fsl/fsl-asoc-card.o 8812 952 0 9764 2624 sound/soc/fsl/fsl-asoc-card.o text data bss dec hex filename 4165 264 8 4437 1155 sound/soc/fsl/imx-wm8962.o 4229 200 8 4437 1155 sound/soc/fsl/imx-wm8962.o Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- sound/soc/fsl/fsl-asoc-card.c | 2 +- sound/soc/fsl/imx-wm8962.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff -u -p a/sound/soc/fsl/fsl-asoc-card.c b/sound/soc/fsl/fsl-asoc-card.c --- a/sound/soc/fsl/fsl-asoc-card.c +++ b/sound/soc/fsl/fsl-asoc-card.c @@ -183,7 +183,7 @@ static int fsl_asoc_card_hw_params(struc return 0; } -static struct snd_soc_ops fsl_asoc_card_ops = { +static const struct snd_soc_ops fsl_asoc_card_ops = { .hw_params = fsl_asoc_card_hw_params, }; diff -u -p a/sound/soc/fsl/imx-wm8962.c b/sound/soc/fsl/imx-wm8962.c --- a/sound/soc/fsl/imx-wm8962.c +++ b/sound/soc/fsl/imx-wm8962.c @@ -61,7 +61,7 @@ static int imx_hifi_hw_params(struct snd return 0; } -static struct snd_soc_ops imx_hifi_ops = { +static const struct snd_soc_ops imx_hifi_ops = { .hw_params = imx_hifi_hw_params, }; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
