[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. Signed-off-by: Ville Syrjala <syrjala@sci.fi> Cc: "Antonino A. Daplas" <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
