puc device

[Jean-Marc Zucconi]

Are there known problems with this device? I can't get it to work
because the driver fails in puc_pci_attach() when allocating
resources at
	res = bus_alloc_resource(dev, SYS_RES_IOPORT, &rid,
		    0ul, ~0ul, 1, RF_ACTIVE);
As this is a pci device and the I/O ports are not used by another
hardware piece, why does bus_alloc_resource() returns NULL here?

This is on a 4.10 system but I tried to boot with a 5.3 kernel and the
behavior is the same.
