One reason the driver claims all the EEPROM addresses used by
each chip is to address review feedback from Jean Delvare.
ISTR the point was safety: letting other drivers potentially
access the device was a bad idea. ;)

Not really. The "eeprom" driver, or various other legacy
drivers knowing about the 0x50..0x57 address range, could
bind to those addresses. That problem would not be solved.
