[PATCH v2] drm/atomic: Use DRM_DEBUG_KMS instead of DRM_DEBUG_ATOMIC in error paths

Ville Syrjala ville.syrjala at linux.intel.com
Wed Nov 15 18:38:41 UTC 2017


From: Ville Syrjälä <ville.syrjala at linux.intel.com>

DRM_DEBUG_ATOMIC generates a lot of noise that no one normally cares
about. However error paths everyone cares about, so hiding thea error
debugs under DRM_DEBUG_ATOMIC is a bad idea. Let's use DRM_DEBUG_KMS
for those instead.

v2: Rebase and handle a few new cases
