From 1bc177174b97e4df8d27b6c3cdd79ffea9e2d18e Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 8 Sep 2016 20:59:01 -0300 Subject: [media] usb: constify vb2_ops structures Check for vb2_ops structures that are only stored in the ops field of a vb2_queue structure. That field is declared const, so vb2_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/) // @r disable optional_qualifier@ identifier i; position p; @@ static struct vb2_ops i@p = { ... }; @ok@ identifier r.i; struct vb2_queue e; position p; @@ e.ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct vb2_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct vb2_ops i = { ... }; // Signed-off-by: Julia Lawall Reviewed-by: Laurent Pinchart Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/usb/s2255/s2255drv.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media/usb/s2255/s2255drv.c') diff --git a/drivers/media/usb/s2255/s2255drv.c b/drivers/media/usb/s2255/s2255drv.c index 9458eb0ef66f..c3a0e87066eb 100644 --- a/drivers/media/usb/s2255/s2255drv.c +++ b/drivers/media/usb/s2255/s2255drv.c @@ -717,7 +717,7 @@ static void buffer_queue(struct vb2_buffer *vb) static int start_streaming(struct vb2_queue *vq, unsigned int count); static void stop_streaming(struct vb2_queue *vq); -static struct vb2_ops s2255_video_qops = { +static const struct vb2_ops s2255_video_qops = { .queue_setup = queue_setup, .buf_prepare = buffer_prepare, .buf_queue = buffer_queue, -- cgit v1.2.3
