Date: Sun, 16 Jul 2017 12:00:44 +0530 From: Arvind Yadav <arvind.yadav.cs@...il.com> To: linux-kernel@...r.kernel.org, linux-rdma@...r.kernel.org, aditr@...are.com, pv-drivers@...are.com, sean.hefty@...el.com, dledford@...hat.com, hal.rosenstock@...il.com Subject: [PATCH 1/3] infiniband: mthca: constify pci_device_id. pci_device_id are not supposed to change at runtime. All functions working with pci_device_id provided by <linux/pci.h> work with const pci_device_id. So mark the non-const structs as const.
