+Subject: [PATCH 67/73] drm/radeon: fix non revealent error message
+
+commit 8d1c702aa0b2c4b22b0742b72a1149d91690674b upstream.
+
+We want to print link status query failed only if it's
+an unexepected fail. If we query to see if we need
+link training it might be because there is nothing
+connected and thus link status query have the right
+to fail in that case.
+
+To avoid printing failure when it's expected, move the
+failure message to proper place.
