Allow /sys/devices/platform/thinkpad_hwmon/hwmon/*/temp2_input

[Bryantdl7]

My thinkpad t495 likes to swap between

/sys/devices/platform/thinkpad_hwmon/hwmon/hwmon5/temp2_input

and

/sys/devices/platform/thinkpad_hwmon/hwmon/hwmon6/temp2_input

as it feels like it, when this happens thinkfan decided to unalive and I have no fan control.

I tried making it /sys/devices/platform/thinkpad_hwmon/hwmon/*/temp2_input but that just errors out, can we get this as a feature in the future?

Here's my work around for the time being for other poor souls on a Thinkpad T495:

/etc/thinkfan.conf

hwmon /dev/hacked-cpu-temperature/temp6_input
hwmon /dev/hacked-cpu-temperature/temp3_input
hwmon /dev/hacked-cpu-temperature/temp7_input
hwmon /dev/hacked-cpu-temperature/temp4_input
hwmon /dev/hacked-cpu-temperature/temp1_input
hwmon /dev/hacked-cpu-temperature/temp5_input
hwmon /dev/hacked-cpu-temperature/temp2_input
