From c236323dfc876be3c45ec3176813e253d713f237 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 5 Aug 2017 06:47:09 -0400 Subject: [PATCH] media: davinci: vpbe: constify vb2_ops structures These vb2_ops structures are only stored in the ops field of a vb2_queue structure, which is declared as const. Thus the vb2_ops structures themselves can be const. Done with the help of Coccinelle. // @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 Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/davinci/vpbe_display.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/platform/davinci/vpbe_display.c b/drivers/media/platform/davinci/vpbe_display.c index ca2adfa565f6..13d027031ff0 100644 --- a/drivers/media/platform/davinci/vpbe_display.c +++ b/drivers/media/platform/davinci/vpbe_display.c @@ -355,7 +355,7 @@ static void vpbe_stop_streaming(struct vb2_queue *vq) spin_unlock_irqrestore(&disp->dma_queue_lock, flags); } -static struct vb2_ops video_qops = { +static const struct vb2_ops video_qops = { .queue_setup = vpbe_buffer_queue_setup, .wait_prepare = vb2_ops_wait_prepare, .wait_finish = vb2_ops_wait_finish, -- 2.11.0
