Subject: [PATCH 3/3] nand: make Open Firmware device id constant
Date: Sat, 09 Jan 2010 15:10:46 +0100 [thread overview]
Message-ID: <4B488E66.6080107@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 xps2_of_match also constant.
The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)
