Subject: [PATCH 9/9] USB goku_udc: make PCI device id constant
Date: Sun, 10 Jan 2010 15:35:23 +0100 [thread overview]
Message-ID: <4B49E5AB.5080309@freemail.hu> (raw)
From: Márton Németh <nm127@freemail.hu>
The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make pci_ids also constant.
The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
