From 0e7c30233f10d834ee26b7d6d32b397625e11e10 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Sat, 22 Feb 2014 16:20:04 +0000 Subject: [PATCH] targets/gbm: exit gracefully if pipe_loader_drm_probe_fd is not available When one builds without gallium_drm_loader, the above function will not be available, thus we'll segfault in gallium_screen_create due to memory access violation.
