Amit Kucheria - Feb. 7, 2019, 10:49 a.m.
We print a calibration failure message on -EPROBE_DEFER from
nvmem/qfprom as follows:
[    3.003090] qcom-tsens 4a9000.thermal-sensor: version: 1.4
[    3.005376] qcom-tsens 4a9000.thermal-sensor: tsens calibration failed
[    3.113248] qcom-tsens 4a9000.thermal-sensor: version: 1.4

This confuses people when, in fact, calibration succeeds later when
nvmem/qfprom device is available. Don't print this message on a
-EPROBE_DEFER.
