From 00f992af585b6e0ec0aa2f173b480a42ada80869 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 5 Aug 2017 06:47:13 -0400 Subject: [PATCH] media: imx: capture: 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/staging/media/imx/imx-media-capture.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/staging/media/imx/imx-media-capture.c b/drivers/staging/media/imx/imx-media-capture.c index ddab4c249da2..ea145bafb880 100644 --- a/drivers/staging/media/imx/imx-media-capture.c +++ b/drivers/staging/media/imx/imx-media-capture.c @@ -62,7 +62,7 @@ struct capture_priv { /* In bytes, per queue */ #define VID_MEM_LIMIT SZ_64M -static struct vb2_ops capture_qops; +static const struct vb2_ops capture_qops; /* * Video ioctls follow @@ -503,7 +503,7 @@ static void capture_stop_streaming(struct vb2_queue *vq) spin_unlock_irqrestore(&priv->q_lock, flags); } -static struct vb2_ops capture_qops = { +static const struct vb2_ops capture_qops = { .queue_setup = capture_queue_setup, .buf_init = capture_buf_init, .buf_prepare = capture_buf_prepare, -- 2.45.2
