media: v4l2-pci-skeleton: 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. // <smpl> @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 = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
