+Subject: nvmem: Use the same permissions for eeprom as for nvmem
+
+From: Jean Delvare <jdelvare@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".
+

+Fixes: b6c217ab9be6 ("nvmem: Add backwards compatibility support for older EEPROM drivers.")
