[hcflinux] hcfpciserial crashes during module installation on reboot

[mdm]

I'm running Gentoo 1.4rc1 on a Pentium2.

make clean, make install, hcfpciconfig all work great. The modem appears as /dev/ttySHCF0, and it dials and connects just fine.

On subsequent reboots, however, hcfpciserial.o causes a segfault while initializing. This results in the module becoming stuck in the "initializing" state, so it can't be removed with rmmod.
