From: Eric Anholt Date: Fri, 27 Sep 2013 18:39:25 +0000 (-0700) Subject: dri: Pass in the dlsym()ed driver extension to screen creation. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f93533d118b6dab00022cc9bc1448615a25946dc;p=mesa.git dri: Pass in the dlsym()ed driver extension to screen creation. This will allow a megadrivers build to reference the actual driver being loaded from the shared dri_util screen creation code. v2: Fix indentation, fallback case in EGL (review by Emil).
