Author: Connor Abbott <[email protected]> Date: Thu Sep 1 14:37:41 2022 +0200 tu/lrz: Fix multiple depth attachment case with secondaries This is a counterpart to the previous commit. When we have multiple depth attachments, in the secondary we currently don't disable LRZ and so we may need a valid LRZ fast-clear base.
