-Subject: Add dummy xf86DisableRandR.
-Patch-mainline: Never
-Author: Michal Srb <msrb@suse.com>
-References: bnc#1089601
-
-This is temporary fix for breakage after backporting upstream patch
-dd00e5466a0e4ea313d1860824da4123692827ed (xorg-server-1.19.0-566-gdd00e5466).
-
-The patch removed function xf86DisableRandR. This patch re-adds it as a dummy function
-that does nothing to fix linking with drivers that expect it. Drivers should no longer
-call it, so putting it back empty has the same effect.
