[PATCH 8/9] tty: serial: jsm: constify pci_device_id.
From: Arvind Yadav
Date: Sun Jul 23 2017 - 06:01:54 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
2442 1088 8 3538 dd2 tty/serial/jsm/jsm_driver.o
File size After adding 'const':
text data bss dec hex filename
3082 448 8 3538 dd2 tty/serial/jsm/jsm_driver.o
