From e0aee8b667955675e2e6c647a88048b64bc2796e Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Tue, 2 May 2017 19:26:17 +0300 Subject: [PATCH] anv: fix possible stack corruption drmGetDevices2 takes count and not size. Probably hasn't caused problems yet in practice and was missed as setups with more than 8 DRM devices are not very common.
