No regressions on Dell XPS 13 (L321X). hw.sensors.acpitz0.temp0 and
hw.sensors.acpitz1.temp0 still go from a normal reading (64 degC) to a
somewhat strange reading (27.80 degC) after suspend/resume. A reboot is
needed to get the normal temperature reading back.
hw.sensors.cpu{0-3}.temp0 continue to output correct readings post
suspend/resume.
