Subject: [PATCH 6/9] tty: serial: pci: constify pci_device_id.
Date: Sun, 23 Jul 2017 15:31:06 +0530 [thread overview]
Message-ID: <1500804069-11043-7-git-send-email-arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1500804069-11043-1-git-send-email-arvind.yadav.cs@gmail.com>
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
12626 18128 0 30754 7822 tty/serial/8250/8250_pci.o
File size After adding 'const':
text data bss dec hex filename
23986 6768 0 30754 7822 tty/serial/8250/8250_pci.o
