thermal: qcom-spmi-temp-alarm: Don't suppress negative temp

2020-09-09T17:12:29+00:00

[ Upstream commit 0ffdab6f2dea9e23ec33230de24e492ff0b186d9 ]

Currently driver is suppressing the negative temperature
readings from the vadc. Consumers of the thermal zones need
to read the negative temperature too. Don't suppress the
readings.

drivers: thermal: qcom: tsens: Fix memory leak from qfprom read

2019-08-28T13:05:08+00:00

memory returned as part of nvmem_read via qfprom_read should be
freed by the consumer once done.
Existing code is not doing it so fix it.

Pull thermal management updates from Zhang Rui:

 - Remove the 'module' Kconfig option for thermal subsystem framework
   because the thermal framework are required to be ready as early as
   possible to avoid overheat at boot time (Daniel Lezcano)

 - Fix a bug that thermal framework pokes disabled thermal zones upon
   resume (Wei Wang)

  - A couple of cleanups and trivial fixes on int340x thermal drivers
    (Srinivas Pandruvada, Zhang Rui, Sumeet Pawnikar)
