From 65f96417363148989bc5b7735b2fc4e824c9d2b9 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Sat, 15 Jul 2017 09:55:51 +0530 Subject: [PATCH] isdn: avm: c4: 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.
