From 90c1284b5806b7c018ff51459b90795f5d53a0aa Mon Sep 17 00:00:00 2001 From: Wambui Karuga Date: Thu, 6 Feb 2020 11:00:03 +0300 Subject: [PATCH] drm/i915/dp_link_training: convert to drm_device based logging macros. Converts various instances of the printk based drm logging macros to the struct drm_device based logging macros in i915/display/intel_dp_link_training.c. This also involves extracting the drm_i915_private device pointer from the intel_dp type to use in the various macros.
