Subject: x86: pci: Don't return a vesa mode when there is not video
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=23609c71dc0c4a433b7189308cda25d1b9e70c43;p=u-boot.git

x86: pci: Don't return a vesa mode when there is not video

If the video has not been set up, we should not return a success code. This
can be detected by seeing if any of the variables are non-zero.
