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 4500 696 0 5196 144c sound/soc/generic/simple-card.o 4564 632 0 5196 144c sound/soc/generic/simple-card.o text data bss dec hex filename 3018 608 0 3626 e2a sound/soc/generic/simple-scu-card.o 3074 544 0 3618 e22 sound/soc/generic/simple-scu-card.o text data bss dec hex filename 4148 2448 768 7364 1cc4 sound/soc/intel/boards/bdw-rt5677.o 4212 2384 768 7364 1cc4 sound/soc/intel/boards/bdw-rt5677.o text data bss dec hex filename 5403 4628 384 10415 28af sound/soc/intel/boards/bxt_da7219_max98357a.o 5531 4516 384 10431 28bf sound/soc/intel/boards/bxt_da7219_max98357a.o text data bss dec hex filename 5275 4496 384 10155 27ab sound/soc/intel/boards/bxt_rt298.o 5403 4368 384 10155 27ab sound/soc/intel/boards/bxt_rt298.o text data bss dec hex filename 10017 2344 48 12409 3079 sound/soc/intel/boards/bytcr_rt5640.o 10145 2232 48 12425 3089 sound/soc/intel/boards/bytcr_rt5640.o text data bss dec hex filename 3719 2356 0 6075 17bb sound/soc/intel/boards/bytcr_rt5651.o 3847 2244 0 6091 17cb sound/soc/intel/boards/bytcr_rt5651.o text data bss dec hex filename 3598 2392 0 5990 1766 sound/soc/intel/boards/cht_bsw_max98090_ti.o 3726 2280 0 6006 1776 sound/soc/intel/boards/cht_bsw_max98090_ti.o text data bss dec hex filename 5343 3624 16 8983 2317 sound/soc/intel/boards/cht_bsw_rt5645.o 5471 3496 16 8983 2317 sound/soc/intel/boards/cht_bsw_rt5645.o text data bss dec hex filename 4662 2592 384 7638 1dd6 sound/soc/intel/boards/cht_bsw_rt5672.o 4790 2464 384 7638 1dd6 sound/soc/intel/boards/cht_bsw_rt5672.o text data bss dec hex filename 1595 2528 0 4123 101b sound/soc/intel/boards/haswell.o 1659 2472 0 4131 1023 sound/soc/intel/boards/haswell.o text data bss dec hex filename 6272 4760 416 11448 2cb8 sound/soc/intel/boards/skl_nau88l25_max98357a.o 6464 4568 416 11448 2cb8 sound/soc/intel/boards/skl_nau88l25_max98357a.o text data bss dec hex filename 7075 4888 416 12379 305b sound/soc/intel/boards/skl_nau88l25_ssm4567.o 7267 4696 416 12379 305b sound/soc/intel/boards/skl_nau88l25_ssm4567.o text data bss dec hex filename 5659 4496 384 10539 292b sound/soc/intel/boards/skl_rt286.o 5787 4368 384 10539 292b sound/soc/intel/boards/skl_rt286.o text data bss dec hex filename 1721 2048 0 3769 eb9 sound/soc/kirkwood/armada-370-db.o 1769 1976 0 3745 ea1 sound/soc/kirkwood/armada-370-db.o text data bss dec hex filename 1363 1792 0 3155 c53 sound/soc/mxs/mxs-sgtl5000.o 1427 1728 0 3155 c53 sound/soc/mxs/mxs-sgtl5000.o Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@kernel.org>
