From c40f716ad34170aec93da145210aacf10599ecb0 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sun, 23 Jul 2017 15:31:06 +0530 Subject: [PATCH] tty: serial: pci: 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.
