Check for snd_pcm_ops structures that are only stored in the ops field of a snd_soc_platform_driver structure or passed as the third argument to snd_pcm_set_ops. The corresponding field or parameter is declared const, so snd_pcm_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_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <redacted> --- sound/soc/amd/acp-pcm-dma.c | 2 +- sound/soc/atmel/atmel-pcm-pdc.c | 2 +- sound/soc/codecs/rt5514-spi.c | 2 +- sound/soc/fsl/fsl_asrc_dma.c | 2 +- sound/soc/intel/atom/sst-mfld-platform-pcm.c | 2 +- sound/soc/intel/haswell/sst-haswell-pcm.c | 2 +- sound/soc/intel/skylake/skl-pcm.c | 2 +- sound/soc/kirkwood/kirkwood-dma.c | 2 +- sound/soc/qcom/lpass-platform.c | 2 +- sound/soc/soc-utils.c | 2 +- 10 files changed, 10 insertions(+), 10 deletions(-)
