[PATCH 22/28] video: fbdev: pm2fb: constify pci_device_id.
From: Arvind Yadav
Date: Thu Jul 20 2017 - 13:42:55 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 After adding 'const':
