| |
From: Márton Németh <nm127@freemail.hu>
The match_table field of the struct of_device_id is constant in <linux/of_platform.h> so it is worth to make ace_of_match 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>
