[Mesa-dev] [PATCH 4.5/13] egl: check for driver_configs in dri2_display_release

[Emil Velikov]

From: Tapani Pälli <tapani.palli at intel.com>

With later commits we'll split and reuse the destroy side of the
function for the initialize_foo error path.

In such cases, driver_configs may be NULL leading to a crash.
