From a15dab756b0f4687a7c3e9e54767f58fbc63c603 Mon Sep 17 00:00:00 2001 From: Suzuki K Poulose Date: Wed, 19 Jun 2019 13:52:53 -0600 Subject: [PATCH] coresight: Make sure device uses DT for obsolete compatible check As we prepare to add support for ACPI bindings, let us make sure we do the compatible check only if we are sure we are dealing with a DT based system.
