[PATCH 28/28] video: fbdev: vt8623fb: constify pci_device_id.

From: Arvind Yadav <hidden>
Date: 2017-07-20 17:41:45
Also in: lkml
Subsystem: framebuffer layer, the rest · Maintainers: Helge Deller, Linus Torvalds

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
  11790	   1913	      0	  13703	   3587	drivers/video/fbdev/vt8623fb.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  11854	   1849	      0	  13703	   3587	drivers/video/fbdev/vt8623fb.o
