[PATCH 1/3] drm/atomic: Improve debug messages
Ville Syrjala
ville.syrjala at linux.intel.com
Mon Jun 11 19:34:01 UTC 2018
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Print the id/name of the object we're dealing with. Makes it easier to
figure out what's going on. Also toss in a few extra debug prints that
might be useful.
