From 50bd842b32b4ef57fdf5381b428d1b5605f429ea Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sun, 23 Jul 2017 15:31:05 +0530 Subject: [PATCH] tty: moxa: 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.
