From e1ec650f9ae7d1e66f77bf14c86e4e9dc629a4d5 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Thu, 6 Jul 2017 23:18:39 +0530 Subject: tpm: tpm_crb: 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.
