If anyone has any objections, please let me know. ------------------ From: Armin Wolf [ Upstream commit 8cf4fdac9bdead7bca15fc56fdecdf78d11c3ec6 ] As specified in section 5.7.2 of the ACPI specification the feature group string "3.0 _SCP Extensions" implies that the operating system evaluates the _SCP control method with additional parameters. However the ACPI thermal driver evaluates the _SCP control method without those additional parameters, conflicting with the above feature group string advertised to the firmware thru _OSI. Stop advertising support for this feature string to avoid confusing the ACPI firmware.
