Subject: [PATCH] leds: make PCI device id constant
Date: Sun, 10 Jan 2010 01:11:03 +0100 [thread overview]
Message-ID: <4B491B17.5070305@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:
