The last description obviously belongs to unchecked_isa_dma.
scan is a write-only attribute that may or may not initiate a bus rescan,

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.
