Hello,

The fancontrol script use configure file: /etc/fancontrol, which use hwmon1
to control the fan.
But the thinkpad_hwmon switch randomly between hwmon0 and hwmon1 after
reboot.

/sys/class/hwmon/
=E2=94=9C=E2=94=80=E2=94=80 hwmon0 -> ../../devices/virtual/hwmon/hwmon0
=E2=94=94=E2=94=80=E2=94=80 hwmon1 -> ../../devices/platform/thinkpad_hwmon=
/hwmon/hwmon1

If thinkpad_hwmon takes hwmon0, the fancontrol script complained about the
config file outdated, suggested to run pwmconfig again.
I have to replace "hwmon1" with "hwmon0" in /etc/fancontrol file to fix it.

How to set the thinkpad_hwmon to a fix position? Thanks!

/etc/fancontrol:
# Configuration file generated by pwmconfig, changes will be lost
INTERVAL=3D10
DEVPATH=3Dhwmon1=3Ddevices/platform/thinkpad_hwmon
DEVNAME=3Dhwmon1=3Dthinkpad
