Subject: x86/vga: set the default device from the fixup.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6cf20beec4b91c240cf759b4db72669e251f1fc4;p=linux-beck.git

x86/vga: set the default device from the fixup.

Since Matthew's efi/vga changes on non-EFI machines we were failing
to tell the vgaarb/switcheroo what the default device was, this
sets the default device in the quirk if none has been set before.

This fixes the switcheroo on my T410s.
