From c1adab97034814d3ccc961cbe027fae505d710ba Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Thu, 18 May 2017 11:31:03 +0000 Subject: [PATCH] drm/i915/guc: Remove failed doorbell stat from debugfs This stat is almost always zero unless fatal error occurs, which should be reported by other means anyway.
