[PATCH 1/5] via686a: make PCI device id constant
From: NÃmeth MÃrton
Date: Mon Jan 04 2010 - 18:44:09 EST
From: MÃrton NÃmeth <nm127@xxxxxxxxxxx>
The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make pci_device_id also constant.
The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
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>
