The id_table field of the struct usb_device_id is constant in <linux/usb.h> so it is worth to make the initialization data also constant. The semantic match that finds this kind of pattern is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ disable decl_init,const_decl_init; identifier I1, I2, x; @@ struct I1 { ... const struct I2 *x; ... }; @s@ identifier r.I1, y; identifier r.x, E; @@ struct I1 y = { .x = E, }; @c@ identifier r.I2; identifier s.E; @@ const struct I2 E[] = ... ; @depends on !c@ identifier r.I2; identifier s.E; @@ + const struct I2 E[] = ...; // </smpl> Signed-off-by: Németh Márton <nm127@freemail.hu> Cc: Julia Lawall <julia@diku.dk> Cc: cocci@diku.dk Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
