From e094d44568680d4e5e2722c4ad090ff0810719b9 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Thu, 23 Jul 2015 18:28:26 +0100 Subject: arm64: kernel: remove non-legit DT warnings when booting using ACPI Since both CONFIG_ACPI and CONFIG_OF are enabled when booting using ACPI tables on ARM64 platforms, we get few device tree warnings which are not valid for ACPI boot. We can use of_have_populated_dt to check if the device tree is populated or not before throwing out those errors. This patch uses of_have_populated_dt to remove non legitimate device tree warning when booting using ACPI tables.
