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.
