[PATCH] Driver core: pass interface to class interface methods

Browse source 
Driver core: pass interface to class intreface methods

Pass interface as argument to add() and remove() class interface
methods. This way a subsystem can implement generic add/remove
handlers and then call interface-specific ones.
