Subject: Fix a problem that caused the new interface code to not actually be
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=71996ddbe191b1289aa5f3d83d6b1c951d79eba0;p=mesa.git

Fix a problem that caused the new interface code to not actually be
used.  Fix a couple problems that confound the fbconfig filtering code
in libGL.
