ALSA: declare snd_kcontrol_new structures as const
Declare snd_kcontrol_new structures as const as they are only passed an argument to the function snd_ctl_new1. This argument is of type const, so snd_kcontrol_new structures having this property can be made const. Done using Coccinelle: @r disable optional_qualifier@ identifier x; position p; @@ static struct snd_kcontrol_new x@p={...}; @ok@ identifier r.x; position p; @@ snd_ctl_new1(&x@p,...) @bad@ position p != {r.p,ok.p}; identifier r.x; @@ x@p @depends on !bad disable optional_qualifier@ identifier r.x; @@ +const struct snd_kcontrol_new x; Cross compiled these files: sound/aoa/codecs/tas.c - powerpc sound/mips/{hal2.c/sgio2audio.c} - mips sound/ppc/{awacs.c/beep.c/tumbler.c} - powerpc sound/soc/sh/siu_dai.c - sh Could not find an architecture to compile sound/sh/aica.c.
