I am not sure about the real problen behind as I did not yet understand it.
10 years ago, I had to write a DPLI driver for a device that does firmware
download via mmap(). The problem is that you need to tell the kernel the
device mmap() information at a time when you do not even know whether the
instance in question is present at all and what parameters to fill in.
What I did was to return a pointer to dummy information that I did overwrite
after I did know the right values.
BTW: fore did not understand this and this was the reason why you could not
move a fore card to another slot without manualy editing /etc/path_to_instance
;-)
