Subject: intel: Remove duplicated teximage miptree to object miptree promotion.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5716ad24255a39f4fb91f9ca28ccfe29e3d4a4b9;p=mesa.git

intel: Remove duplicated teximage miptree to object miptree promotion.

intel_finalize_mipmap_tree() does this optimization too, just more
aggressively.
