Public bug reported:
thermald uninitialised member causes loss of temperature control, the
patch 0002-Don-t-keep-on-reading-a-sensor-if-the-temperature-is.patch,
added in 1.7.0-5, introduces a new cthd_sensor data member
temp_unreadable but fails to initialise it.
This causes nondeterministic behaviour. If any bits of the uninitialised
boolean are nonzero, it will be evaluate to true, and the sensor will be
silently disabled, causing loss of temperature control.
This bug is critical because loss of temperature control risks physical
hardware damage.
