Subject: [PATCH] edac: make Open Firmware device id constant
Date: Sun, 10 Jan 2010 12:20:27 +0100	[thread overview]
Message-ID: <4B49B7FB.4020402@freemail.hu> (raw)

From: Márton Németh <nm127@freemail.hu>

The match_table field of the struct of_device_id is constant in <linux/of_platform.h>
so it is worth to make the initialization data constant.

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