By doing so, you won't be able to remove the module after that. While the
module has a usage count of 0, there are module dependancies which prevent
removal until those module are gone. The 8390 is not really a driver (a
device) but a library of function shared between different drivers, so it
has no real usage count.
I think the current situation is correct and your patch is not needed. On
my system, /proc/modules shows (stripped version)
ne 2 1
8390 2 [ne] 0
You can't rmmod (modprobe -r) a module with a usage count > 0.
