hwmon: (k8temp) Fix temperature reporting for ASB1 processor revisions
Reported temperature for ASB1 CPUs is too high. Add ASB1 CPU revisions (these are also non-desktop variants) to the list of CPUs for which the temperature fixup is not required. Example: (from LENOVO ThinkPad Edge 13, 01972NG, system was idle) Current kernel reports $ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +74.0 C Core0 Temp: +70.0 C Core1 Temp: +69.0 C Core1 Temp: +70.0 C With this patch I have $ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +54.0 C Core0 Temp: +51.0 C Core1 Temp: +48.0 C Core1 Temp: +49.0 C Cc: stable@kernel.org [.32.x .33.x, .34.x] Cc: Rudolf Marek <r.marek@assembler.cz> Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
