Subject: [lm-sensors] [PATCH 2/5] vt8231: make PCI device id constant
Date: Mon, 04 Jan 2010 23:44:00 +0000	[thread overview]
Message-ID: <4B427D40.3010102@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_device_id also constant.

The semantic match that finds this kind of pattern is as follows:
