[PATCH 3/9] tty: synclinkmp: constify pci_device_id.
From: Arvind Yadav
Date: Sun Jul 23 2017 - 06:03:34 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
44660 432 104 45196 b08c drivers/tty/synclinkmp.o
File size After adding 'const':
text data bss dec hex filename
44756 336 104 45196 b08c drivers/tty/synclinkmp.o
