Note that this is the patch which have the above title. So I don't know
if you have to drop the patch or just change the title to an appropriate
one.

Tony

The patch titled
     ignore vgacon if hardware not present
has been removed from the -mm tree.  Its filename was
     ignore-vgacon-if-hardware-not-present.patch

This patch was dropped because it was merged into mainline or a
subsystem tree

Avoid trying to set up vgacon if there's no vga hardware present.
