Add generic __to_intel_display() macro that accepts either struct drm_i915_private * or struct intel_display *. This is to be used for transitional stuff that eventually needs to be converted to use struct intel_display *, and therefore is not part of to_intel_display(). Add new intel_display_conversion.h to host the helper to avoid duplication between xe and i915 drivers. v2: put it in the new header (Rodrigo) Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/a999ff8183659a4df68d439ebd31c19b5c56852a.1713358679.git.jani.nikula@intel.com
