From ff890bc00830830799a72ed7481836f0dd9c3be9 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Thu, 6 Jul 2017 22:25:56 +0530 Subject: [PATCH] extcon: int3496: Constify acpi_device_id acpi_device_id are not supposed to change at runtime. All functions working with acpi_device_id provided by work with const acpi_device_id. So mark the non-const structs as const.
