[Mesa-dev] [PATCH 06/13] i965/miptree: Delete MIPTREE_CREATE_LINEAR

[Nanley Chery]

This enum constant was introduced to enable blit maps with intel_miptree_create
da2880bea05bfc87109477ab026a7f5401fc8f0c. Now that such maps use the more
direct make_surface function which allows you to specify the tiling directly,
the constant is no longer being used.
