From d02bbde1a8e6b96ca3b2e0d160c966dcb63d6c16 Mon Sep 17 00:00:00 2001 From: Bas Nieuwenhuizen Date: Mon, 9 Apr 2018 23:16:55 +0200 Subject: radv: Use sorted bindings for set layout creation. Previously we did not care about havin the set storage in order, but for variable descriptor count we want the highest binding at the end of the storage.
