Subject: [PATCH 5.8 112/186] thermal: qcom-spmi-temp-alarm: Dont suppress negative temp

From: Veera Vegivada <vvegivad@...eaurora.org>

[ 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.
