From 0846b762c42d9654290f19a3b2e6248d6aca2b0a Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sun, 23 Jul 2017 15:31:09 +0530 Subject: [PATCH] tty: synclink_gt: 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.
