The patch titled
Subject: platform-x86: intel_mid_thermal: turn off thermistor voltage by default
has been removed from the -mm tree. Its filename was
platform-x86-intel_mid_thermal-turn-off-thermistor-voltage-by-default.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: platform-x86: intel_mid_thermal: turn off thermistor voltage by default
Instead of complaining that the voltage is on, we can just ask the MSIC to
turn the voltage off. This should save some power.
Voltage for thermistors is turned on when ADC conversion is initiated.
