module is not unloaded when probe fails

module is not unloaded when probe fails

[Giuliano Pochini]

When I try to load a module and it fails (snd-darla20 in this case) the
module is not unloaded. IIRC it didn't happen some months ago, but I have no
idea what is the cause because I changed a lot of stuff in the meantime
(kernel, compiler, modutils...). Is this the expected behaviour ?

Yes, it's by design. If a module sees it can't drive the available
hardware, it *should* stay loaded so you either can
- add new hardware it can drive or
- tell it via /sys/bus/pci/drivers/tulip/new_id that it should drive dome
hardware with previously unknown pci id.

It's a new 2.6 feature.
