From 86ab0b1c42b735bf6ae273ffba7b423dcc0c6de4 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 6 Aug 2017 04:25:19 -0400 Subject: media: vim2m: constify v4l2_m2m_ops structures The v4l2_m2m_ops structures are only passed as the only argument to v4l2_m2m_init, which is declared as const. Thus the v4l2_m2m_ops structures themselves can be const. Done with the help of Coccinelle. // @r disable optional_qualifier@ identifier i; position p; @@ static struct v4l2_m2m_ops i@p = { ... }; @ok1@ identifier r.i; position p; @@ v4l2_m2m_init(&i@p) @bad@ position p != {r.p,ok1.p}; identifier r.i; struct v4l2_m2m_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct v4l2_m2m_ops i = { ... }; // Signed-off-by: Julia Lawall Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/vim2m.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media/platform/vim2m.c') diff --git a/drivers/media/platform/vim2m.c b/drivers/media/platform/vim2m.c index 970b9b6dab25..afbaa35ab205 100644 --- a/drivers/media/platform/vim2m.c +++ b/drivers/media/platform/vim2m.c @@ -983,7 +983,7 @@ static struct video_device vim2m_videodev = { .release = video_device_release_empty, }; -static struct v4l2_m2m_ops m2m_ops = { +static const struct v4l2_m2m_ops m2m_ops = { .device_run = device_run, .job_ready = job_ready, .job_abort = job_abort, -- cgit v1.2.3
