[PATCH 1/5] drm: radeon: constify pci_device_id.

From: Arvind Yadav
Date: Sat Jul 15 2017 - 03:13:05 EST


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

File size before:
text data bss dec hex filename
6560 23212 72 29844 7494 gpu/drm/radeon/radeon_drv.o

File size After adding 'const':
text data bss dec hex filename
28960 812 72 29844 7494 gpu/drm/radeon/radeon_drv.o
