From 32791a05024d54736eab21379e849480fea78559 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 19 Mar 2018 20:02:58 +0000 Subject: [PATCH] radv: don't export NULL layer. We have some cases where in subpass we want the layer but having it be 0 and loaded in the frag shader without the vertex shader exporting it is fine. So don't export the layer if we don't have a value to put in it. Fixes: d4c74aed7a8 (radv/multiview: mark layer_input if we have input attachments.)
