which bogus kfree do you mean?  I see a kfree in udsl_destroy_instance,
but it looks fine to me...

For me the main problem with getting these changes into the kernel tree
is that they are not backwards compatible:
(1) the ioctl for signalling that firmware has been loaded from
userspace has gone.  It is still possible to load things from userspace,
by unbinding the kernel driver, loading the firmware, then rebinding it,
but the old modem_run method will no longer work.
(2) the ATM device is only created once the USB device is fully
initialized, not straight away like now.  This may cause trouble for
scripts.  What is more, the ATM layer does not yet support sysfs
(hotplugging).

OK.

The beginning of the working weekend!
