From: Jean Delvare <jdelv...@suse.de>

commit e70d8b287301eb6d7c7761c6171c56af62110ea3 upstream.

The compatibility "eeprom" attribute is currently root-only no
matter what the configuration says. The "nvmem" attribute does
respect the setting of the root_only configuration bit, so do the
same for "eeprom".
