Ok, that doesn't help :-(
I hoped you show me a way how to set the class of adapter. My clients
are loaded with insmod, so dts has no effect (or is this wrong?)
The current situation is:
I can't see a method beside force to instantiate a client at runtime.
But force bypasses clients detect method and is deprecated anyway if I
got Jean right.
Currently I'm lost. Jean NACKs all attempts to do detected client
instantiations at runtime, you do a NACK on making adapter working
properly by indicating to patches that have no more relevance.
Can't anybody help me?
