2020-02-12ASoC: wm0010: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertenly introduced[3] to the codebase from now on. This issue was found with the help of Coccinelle.

Check for snd_soc_codec_driver structures that are only passed to snd_soc_register_codec or memcpy (2nd arg), for which the corresponding parameters are declared const. Declare as const snd_soc_codec_driver structures that have these properties. 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_codec_driver i@p = { ... }; @ok@ identifier r.i; expression e1,e2,e3; position p; @@ ( snd_soc_register_codec(e1,&i@p,e2,e3) | memcpy(e1,&i@p,e2) ) @bad@ position p != {r.p,ok.p}; identifier r.i; @@ i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_soc_codec_driver i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-08-08ASoC: codec duplicated callback function goes to component on wm0010Kuninori Morimoto1-4/+6
