    ALSA: declare snd_kcontrol_new structures as const · 905e46ac
    Bhumika Goyal authored
    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;
