From 6c41a2ef3b72f9465646fea7ac941e8deb14444b Mon Sep 17 00:00:00 2001 From: Nanley Chery Date: Wed, 2 May 2018 20:05:08 -0700 Subject: i965: Prepare to delete intel_miptree_alloc_ccs() We're going to delete intel_miptree_alloc_ccs() in the next commit. With that in mind, replace the use of this function in do_single_blorp_clear() with intel_miptree_alloc_aux() and move the delayed allocation logic to it's callers. v2: Duplicate the delayed allocation comment (Topi Pohjolainen).
