Subject: i965: Make texture validation code use texture objects, not units.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ab1f2e6bc401636202f93efad3677f26d028e412;p=mesa.git

i965: Make texture validation code use texture objects, not units.

This requires moving the _MaxLevel handling up to the callers.  Another
user of intel_finalize_mipmap_tree will be added later that depends on
_MaxLevel not being modified.
