commit 7a72c78bdd0a1ea1d879610542679cc680398220 Author: Rodrigo Vivi <rodrigo.vivi@intel.com> Date: Thu Jul 19 17:31:55 2018 -0700 drm/i915: Fix psr sink status report. First of all don't try to read dpcd if PSR is not even supported. But also, if read failed return -EIO instead of reporting via a backchannel. v2: fix dev_priv: At this level m->private is the connector. (CI/DK) don't convert dpcd read errors to EIO.
