[CI,1/5] drm/i915/overlay: convert to struct intel_display

Message ID 3680586c05e82fd01d173cfb4f8df015d6db663c.1732102179.git.jani.nikula@intel.com (mailing list archive)

Commit Message

Jani Nikula Nov. 20, 2024, 11:30 a.m. UTC
struct intel_display replaces struct drm_i915_private as the main
display device pointer. Convert overlay to it, as much as possible.
