From fa77464ffe14be9532b861b33f57f5c1d63a4824 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 18 Nov 2020 09:16:42 +0000 Subject: contrib/vhost-user-gpu: avoid g_return_val_if() input validation Do not validate input with g_return_val_if(). This API is intended for checking programming errors and is compiled out with -DG_DISABLE_CHECKS. Use an explicit if statement for input validation so it cannot accidentally be compiled out.
