From: Stephen Hemminger Date: Mon, 28 Mar 2011 16:12:52 +0000 (-0700) Subject: drivers: make device_type const X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=aed65af1cc2f6fc9ded5a8158f1405a02cf6d2ff;p=deliverable%2Flinux.git drivers: make device_type const 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.
