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>

struct I1 {

I've merged all 5 patches are they are doing the exact same thing to 5
drivers. The resulting patch is applied, thanks.
