  * X server does not support mixing fbdev with other drivers, so
    claiming pci slots when a fb slot is already claimed only leads
    to quiting with fatal error. (bsc#1119431)

+Subject: xfree86: Do not claim pci slots if fb slot is already claimed.
+Patch-Mainline: To be upstreamed
+References: bsc#1119431
+
+The xf86PostProbe would terminate with fatal error if both fb and pci
+slot were claimed at the same time, so there is no point in trying.
+The opposite logic is already implemented - fb slots will not be claimed
+if a pci slot was claimed.
+
+This fixes issue with xf86-video-fbdev and xf86-video-vesa activating at
+the same time (when /dev/fb0 is provided by the vesafb kernel driver).
