w1: w1_therm: Rename conflicting sysfs attribute 'eeprom' to 'eeprom_cmd'
Duplicate attribute 'eeprom' is defined in: 1) Documentation/ABI/testing/sysfs-driver-w1_therm 2) Documentation/ABI/stable/sysfs-driver-w1_ds28e04 Both drivers define an attribute: /sys/bus/w1/devices/.../eeprom with conflicting behavior. Fix by renaming the newer one in w1_therm.c to 'eeprom_cmd'.
