[PATCH 2/9] tty: isicom: constify pci_device_id.
From: Arvind Yadav
Date: Sun Jul 23 2017 - 06:03:18 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
12176 1520 25864 39560 9a88 drivers/tty/isicom.o
File size After adding 'const':
text data bss dec hex filename
12528 1168 25864 39560 9a88 drivers/tty/isicom.o
