[Intel-gfx] [PATCH] drm/i915: Show debugfs dpcd read failure directly

2018-07-20 Thread Rodrigo Vivi
Instead of using a backchannel if some dpcd read failed we can show that directly on debugfs output. We are not returning an error because we might still want to know if sub-sequent reads works, but we shouldn't need to check 2 places to see why reg is not on the list. Cc: Jani Nikula Cc: Dhinak
