media: st-delta: constify v4l2_m2m_ops structures
The v4l2_m2m_ops structures are only passed as the only argument to v4l2_m2m_init, which is declared as const. Thus the v4l2_m2m_ops structures themselves can be const. Done with the help of Coccinelle. // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct v4l2_m2m_ops i@p = { ... }; @ok1@ identifier r.i; position p; @@ v4l2_m2m_init(&i@p) @bad@ position p != {r.p,ok1.p}; identifier r.i; struct v4l2_m2m_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct v4l2_m2m_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>
