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 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_pcm_ops i@p = { ... }; @ok1@ identifier r.i; struct snd_soc_platform_driver e; position p; @@ e.ops = &i@p; @ok2@ identifier r.i; expression e1, e2; position p; @@ snd_pcm_set_ops(e1, e2, &i@p) @bad@ position p != {r.p,ok1.p,ok2.p}; identifier r.i; struct snd_pcm_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct snd_pcm_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- sound/pci/ad1889.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sound/pci/ad1889.c b/sound/pci/ad1889.c index 1fc6d8b..8c36990 100644 --- a/sound/pci/ad1889.c +++ b/sound/pci/ad1889.c @@ -571,7 +571,7 @@ snd_ad1889_capture_pointer(struct snd_pcm_substream *ss) return bytes_to_frames(ss->runtime, ptr); } -static struct snd_pcm_ops snd_ad1889_playback_ops = { +static const struct snd_pcm_ops snd_ad1889_playback_ops = { .open = snd_ad1889_playback_open, .close = snd_ad1889_playback_close, .ioctl = snd_pcm_lib_ioctl, @@ -582,7 +582,7 @@ static struct snd_pcm_ops snd_ad1889_playback_ops = { .pointer = snd_ad1889_playback_pointer, }; -static struct snd_pcm_ops snd_ad1889_capture_ops = { +static const struct snd_pcm_ops snd_ad1889_capture_ops = { .open = snd_ad1889_capture_open, .close = snd_ad1889_capture_close, .ioctl = snd_pcm_lib_ioctl, -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
