Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
Kernel 7.2 contains the sources for the new Arctic Fan Controller, but it's not enabled.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I installed the controller in my NAS, connected power and USB.

   * What was the outcome of this action?
It's found on USB:

# lsusb | grep 3904
Bus 001 Device 002: ID 3904:f001 ARCTIC (HK) ARCTIC Fan Controller

But no hwinfo device is there:

# cat /sys/class/hwmon/hwmon*/name
acpitz
drivetemp
drivetemp
drivetemp
drivetemp
asus
coretemp

   * What outcome did you expect instead?

A device with name 'arctic_fan' should be there.
