Subject: [PATCH 05/44] drivers: make device_type const
Date: Thu, 19 May 2011 17:10:23 -0700 [thread overview]
Message-ID: <1305850262-9575-5-git-send-email-gregkh@suse.de> (raw)
In-Reply-To: <1305850262-9575-1-git-send-email-gregkh@suse.de>
From: Stephen Hemminger <shemminger@vyatta.com>
The device_type structure does not contain data that changes
during usage and should be const. This allows devices to declare
the struct const.
I have patches to change all the subsystems, but need the infra
structure change first.
