Subject: [PATCH v1 13/13] ACPI: thermal: Rename structure fields holding temperature in deci-Kelvin
From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>
Subject: [PATCH v1]
Rename structure fields holding temperature values in deci-Kelvin so as
to avoid temperature units confusion.
No intentional functional impact.
