But this still can cause the problem that your 'modalias' file in sysfs
contains exactly the same name as the module itself, right?

That's not good, it should be an alias, not the "real name".

I'd even settle for 'driver:MODULE_NAME' and have that automatically
generated by the driver core logic somehow (note, Kay came up with that
idea in the past, it's not new...)

So, I don't like this patch, can't we come up with a way for the alias
to be just that, an alias?

That will ensure that userspace tools do not get confused, _and_ it be
possible to properly use the 'blacklist' option to modprobe (which only
works on aliases right now, as it should.)

thanks,
