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).
