[PATCH] firewire: core-device: constify device_type structures

From: Bhumika Goyal
Date: Sat Jan 21 2017 - 12:01:54 EST


Declare device_type structures as const as they are only stored in the type
field of a device structure. This field is of type const, so device_type
structures having similar properties can be declared const too.
