[PATCH 4/9] tty: synclink: constify pci_device_id.

From: Arvind Yadav
Date: Sun Jul 23 2017 - 06:03:05 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
51755 400 513 52668 cdbc drivers/tty/synclink.o

File size After adding 'const':
text data bss dec hex filename
51883 304 513 52700 cddc drivers/tty/synclink.o
