Subject: [PATCH 05/44] drivers: make device_type const

From: Stephen Hemminger <shemminger@...tta.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.
