can't rmmod cfi_cmdset_0002

[Galen Seitz]

In the course of hacking on pci.c, I've encountered an issue with removing
the cfi_cmdset_0002 module.  It seems that once I have successfully
loaded the pci module, I can't unload the cmdset module.  Is it likely
that I have created this problem?  How does one go about tracking
down a problem like this?

thanks,
galen
