From 18c8832523c8509551ee9354225446125aba10d3 Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Sat, 11 Jan 2020 23:11:12 +0000 Subject: [PATCH] drm/i915/guc: Introduce CT_ERROR We should start using dev variants of error logging and to simplify that introduce helper macro that will do any necessary conversions to obtain pointer to device struct.
