Subject: [PATCH] i2c: make PCI device id constant
Date: Sun, 10 Jan 2010 15:33:08 +0100	[thread overview]
Message-ID: <4B49E524.1090404@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 initialization data also constant.

The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)
