The patch ASoC: constify snd_soc_ops structures has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From ddba7fa4cfd16b10adcbe24fa1d3b7de470af863 Mon Sep 17 00:00:00 2001 From: Julia Lawall <Julia.Lawall@xxxxxxx> Date: Sat, 15 Oct 2016 16:55:50 +0200 Subject: [PATCH] ASoC: constify snd_soc_ops structures 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> Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> --- sound/soc/fsl/fsl-asoc-card.c | 2 +- sound/soc/fsl/imx-wm8962.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/sound/soc/fsl/fsl-asoc-card.c b/sound/soc/fsl/fsl-asoc-card.c index dffd549a0e2a..9998aea23597 100644 --- 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(struct snd_pcm_substream *substream, 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 --git a/sound/soc/fsl/imx-wm8962.c b/sound/soc/fsl/imx-wm8962.c index 201a70d1027a..1b60958e2080 100644 --- 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_pcm_substream *substream, 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, }; -- 2.8.1 -- 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
