From 01fa2fae5a0b0f1c7c7c4afb336fff0278161432 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Mon, 17 Jul 2017 21:39:00 +0530 Subject: [PATCH] dmaengine: ioat: 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.
