I have hardware with multiple ds2482 devices (i2c to 1-wire bridge).  Each instantiation of a ds2482 results in a new w1_bus_master%d device.  However, I cannot figure out how to correlate the w1_bus_master%d device to the original ds2482 device (from user space looking at sysfs entries).  Each master has the same type of device behind it (a ds2433 eeprom), but I still need to know which is which.  The i2c devices (and thus the w1_bus_master%d devices) do not necessarily probe consecutively, so I can't just presume a mapping at any instance in time.  Am I missing something?  Currently on 4.9.189 (debian:9), but am planning to move to 4.19.118 (debian:10).
