[PATCH] pci: yenta cardbus fix

In -mm1 the cardbus resources might be assigned in pci_assign_unassigned_resources() pass. From your dmesg: PCI: Bus 2, cardbus bridge: 0000:00:0b.0 IO window: 00002000-00002fff IO window: 00003000-00003fff PREFETCH window: 12000000-13ffffff MEM window: 14000000-15ffffff Then yenta_allocate_res() tries to assign these resources again and, naturally, fails. This adds check for already assigned cardbus resources. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
