Subject: [PATCH] fbdev: geocode: remove unneeded NULL check

the check for info is not required as we are checking it immediately
after gx1fb_init_fbinfo() and returnig -ENOMEM if it is NULL.

Hi sorry for off topic question, but how do you run 3.20 on geode ?
I was not able to boot anything since 2.27 as initrd (I guess udev )
corrupts (I guess memory something) and boot hangs.
One suggested to bisect but no one explained how.
I would be glad to get some hint on how to run kernel with udev support on
geode (means >= 2.27)

thanks

Tinycore has certainly been reported to run on Geode boxes as of 3.x
kernel series. It might be worth trying a tinycore build on the device
just to see how far it gets on your hardware.
