From: Jerome Glisse Date: Tue, 17 Jul 2012 21:17:16 +0000 (-0400) Subject: drm/radeon: fix non revealent error message X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8d1c702aa0b2c4b22b0742b72a1149d91690674b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/radeon: fix non revealent error message 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.
