There was a memory leak in the HSCX driver and in the Fritz PCI driver. This
leak was obviously fixed only for the HSCX driver and in the Fritz PCI driver
in the new-bus (layer1-nb) directory but not in the old-bus/NetBSD (layer1)
directory for the i4b_avm_fritz_pci.c file.
Please apply the following patch to your copy of i4b_avm_fritz_pci.c (and
don't forget to tell us if it solved the problem):
