[PATCH v2 4/7] drm/client: switch to drm device based logging, and more
Jani Nikula
jani.nikula at intel.com
Mon Apr 8 09:23:59 UTC 2024
Switch to drm device based logging and WARNs, and unify connector and
crtc logging formats. Pass drm device around a bit more to be able to do
this. Drop logging for -ENOMEM.
