The last description obviously belongs to unchecked_isa_dma. scan is a write-only attribute that may or may not initiate a bus rescan, I suppose. proc_name is the "name of proc directory" of a driver, if the driver maintained one; though it seems all drivers provide proc_name independently of the obsolete proc interface for driver data. -- Stefan Richter -=====-==-== =--- =--=- http://arcgraph.de/sr/
