I've tried to reproduce the problem doing various tests -- but without
success.

Then i've checked the code and there was already this fix:

commit e468c04894f36045cf93d1384183a461014b6840 (Gigaset: permit module unload)

This was commited after 2.6.24 was released.

And (shit happens!) on the machine where I've previously tested the
stuff I had also an 2.6.24 kernel installed.

So it seems that I have mixed up different kernel versions when I've
tested my patch. Because with current git-tree bas_gigaset can be
unloaded without any problems.

Sorry for the noise.

Andreas
