[RFT 07/13] s390: tape_3590: constify ccw_device_id

From: Arvind Yadav
Date: Tue Aug 15 2017 - 06:36:43 EST


ccw_device_id are not supposed to change at runtime. All functions
working with ccw_device_id provided by <asm/ccwdev.h> work with
const ccw_device_id. So mark the non-const structs as const.
