Re: [PATCH] drm: Skip drm_mode_config_validate() for !modeset

Quoting Ville Syrjala (2020-03-18 18:25:18)

From: Ville Syrjälä ville.syrjala@linux.intel.com

drm_mode_config_init() may not have been called when the driver/device doesn't support modeset. That will cause drm_mode_config_validate() to oops. Skip the validation for !modeset.

TODO: We may want to consider calling drm_mode_config_init() unconditionally to avoid similar issues elsewhere...
