    [media] pci: constify snd_pcm_ops structures · 5c8d8c01
    Julia Lawall authored
    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
    The semantic patch that makes this change is as follows:
    // <smpl>
    @r disable optional_qualifier@
    identifier i;
    position p;
    static struct snd_pcm_ops i@p = { ... };
    identifier r.i;
    struct snd_soc_platform_driver e;
    position p;
    e.ops = &i@p;
    identifier r.i;
    expression e1, e2;
    position p;
    snd_pcm_set_ops(e1, e2, &i@p)
    position p != {r.p,ok1.p,ok2.p};
    identifier r.i;
    struct snd_pcm_ops e;
    @depends on !bad disable optional_qualifier@
    identifier r.i;
     struct snd_pcm_ops i = { ... };
    // </smpl>
