[Intel-xe] [PATCH 09/10] fixup! drm/xe/display: Implement display support

Jani Nikula jani.nikula at intel.com
Tue Oct 3 14:34:56 UTC 2023


Let the display code decide whether display hardware is there or
not. Remove has_display member from struct xe_device_desc, and
enable_display from struct xe_device.
