Bug#618261: udlfb not acting as console

[jan@uos.de]

Hi!

I would also like to add my +1 vote to enable this option on all
architectures.

I can also confirm, that loading this driver no longer redirects console
output to the DisplayLink adapter right away. Instead, it is now an
option, which is disabled by default. From
http://git.kernel.org/?p=linux/kernel/git/next/linux-next-history.git;a=blob;f=Documentation/fb/udlfb.txt;hb=HEAD :

  console  Allow fbcon to attach to udlfb provided framebuffers. This
           is disabled by default because fbcon will aggressively consume
           the first framebuffer it finds, which isn't usually what the
           user wants in the case of USB displays.

So it seems safe to me, also confirmed by my own testing, to set
CONFIG_FB_UDL=m by default.

Regards!
Jan
