From 3637c46032515fe975f652d315ccd2076026c522 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sun, 23 Jul 2017 15:31:07 +0530 Subject: [PATCH] tty: serial: exar: constify pci_device_id. pci_device_id are not supposed to change at runtime. All functions working with pci_device_id provided by work with const pci_device_id. So mark the non-const structs as const.
