[igt-dev] [PATCH i-g-t 2/5] tests/kms_tiled_display: Replace the igt_display pointer with a struct

[Ville Syrjala <ville.syrjala@linux.intel.com>]

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

No point in storing a pointer when we can just store the struct itself.
The lifetime is the same.
