Hello,
can someone give me a hint how to make attached module working again?
With linux kernel 2.6.16.55 everything is fine but with 2.6.18.8
kobject_add fails and with 2.6.23 the driver OOPS in nokia_probe. The
problems are for example
serial->interface->altsetting[0].endpoint[0].desc.bEndpointAddress and
serial->interface->altsetting[1].endpoint[0].desc.bEndpointAddress. I
think i oversaw the changes in the diffs between the kernel versions.
Thank in advance and regards,
Dirk
