From eb6944f2fc01d5c83bce37fa0e68810565f78a75 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 12 Aug 2015 16:32:05 +0200 Subject: [PATCH] vgaarb: Stop complaining about absent devices Some setups do not register a default VGA device, in which case the VGA arbiter will still complain about the (non-existent) PCI device being a non-VGA device. Fix this by making the error message conditional on a default VGA device having been set up. Note that the easy route of erroring out early isn't going to work because otherwise priv->target won't be properly updated.
