Subject: [PATCH 4/5] input: make pnp device id constant
Date: Sat, 09 Jan 2010 13:56:11 +0100 [thread overview]
Message-ID: <4B487CEB.60003@freemail.hu> (raw)
From: Márton Németh <nm127@freemail.hu>
The id_table field of the struct pnp_driver is constant in <linux/pnp.h>
so it is worth to make pnp_devids also constant.
The semantic match that finds this kind of pattern is as follows:
