[RESEND PATCH 7/9] eeprom: at24: add the at24cs series to the list of supported devices

From: Bartosz Golaszewski
Date: Tue Oct 20 2015 - 04:45:31 EST


The infrastructure for reading of the factory-programmed serial number
for at24cs EEPROM series is now in place. Add the chips that are actually
equipped with the serial number memory area to the list of supported
devices.
