[PATCH 3/8] drm/client: Streamline mode selection debugs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Get rid of all the redundant debugs and just wait until the end
to print which mode (and of which type) we picked.
