From 09a0dc650d8f4c4ed319d302a78252c181b8db6c Mon Sep 17 00:00:00 2001 From: Nicholas Sudsgaard Date: Sun, 10 Mar 2024 22:23:40 +0900 Subject: drivers/acpi/thermal_zone: Correct Kelvin constant used for conversion As 0C is 273.15K you could argue that 2731 and 2732 are both correct. However, 2732 is deemed as correct both throughout the codebase and in the ACPI specification[1].
