From 63f2ec67fa3be6df8d89b74f211cfefe1a58829a Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 4 Aug 2017 08:09:47 -0400 Subject: media: tm6000: constify videobuf_queue_ops structures These videobuf_queue_ops structures are only passed as the second argument to videobuf_queue_vmalloc_init, which is declared as const. Thus the videobuf_queue_ops structures themselves can be const. Done with the help of Coccinelle. // @r disable optional_qualifier@ identifier i; position p; @@ static struct videobuf_queue_ops i@p = { ... }; @ok1@ identifier r.i; expression e1; position p; @@ videobuf_queue_vmalloc_init(e1,&i@p,...) @bad@ position p != {r.p,ok1.p}; identifier r.i; struct videobuf_queue_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct videobuf_queue_ops i = { ... }; // Signed-off-by: Julia Lawall Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/tm6000/tm6000-video.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/usb/tm6000/tm6000-video.c b/drivers/media/usb/tm6000/tm6000-video.c index cec1321289df..ec8c4d2534dc 100644 --- a/drivers/media/usb/tm6000/tm6000-video.c +++ b/drivers/media/usb/tm6000/tm6000-video.c @@ -801,7 +801,7 @@ static void buffer_release(struct videobuf_queue *vq, struct videobuf_buffer *vb free_buffer(vq, buf); } -static struct videobuf_queue_ops tm6000_video_qops = { +static const struct videobuf_queue_ops tm6000_video_qops = { .buf_setup = buffer_setup, .buf_prepare = buffer_prepare, .buf_queue = buffer_queue, -- cgit
