[PATCH 08/28] video: fbdev: tridentfb: constify pci_device_id.

From: Arvind Yadav
Date: Thu Jul 20 2017 - 13:46:31 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
13206 1232 40 14478 388e video/fbdev/tridentfb.o

File size After adding 'const':
text data bss dec hex filename
13910 528 40 14478 388e video/fbdev/tridentfb.o
