I was trying this series on linux-next with Srini's eeprom v4 and my
first attempt was to build the eeprom, qfprom and tsens drivers as
built-in. Unfortunately, the tsens driver probed before the
eeprom/qfprom driver so failed here with the "calibration failed"
message.
Building things as modules worked better, but you might want to take a
look at possibly using -EPROBE_DEFER here?
