From 5cb1cad0aef8d1c426207c955996278290e19e60 Mon Sep 17 00:00:00 2001 From: Emil Velikov Date: Mon, 2 Jun 2014 12:26:17 +0100 Subject: [PATCH] egl/dri2: do not leak dri2_dpy->driver_name Originally all hardware drivers duplicate the driver_name string from an external source, while for the software rasterizer we set it to "swrast". Follow the example set by hw drivers this way we can free the string at dri2_terminate(). v2: Use strdup over strndup. Suggested by Ilia Mirkin. v3: Handle platform_drm in a similar manner. Cleanup swrast driver_name in error path.
