55 # Currently, don't support eeprom db on Arista platform
56 platforms_without_eeprom_db = ['arista', 'kvm']
57 if any(platform in platform_path for platform in platforms_without_eeprom_db)
58 or t.getattr('read_eeprom_db', None) == None:
59 support_eeprom_db = False

If the above line 58 is changed to
getattr(t, 'read_eeprom_db'):
issue is not seen.

We think the issue can be seen in other platforms also as the changes done in platform independent code is causing issue.
