From 6c5a266029cc9b036643d08c2f9340d09ee03708 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Tue, 18 Jul 2017 22:35:06 +0530 Subject: [PATCH] ALSA: hda: 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.
