[PATCH] atyfb: Improve atyfb_atari_probe()
Improve atyfb_atari_probe():
* Call correct_chipset() so that more par members, par->features in
particular, get initialized.
* If probe fails iounmap() the mapped regions and continue probing for more
adapters.
Only verified to cross-compile due to lack of hardware.
