Background and Motivation
-------------------------
When the `hwmon-path-abs` and the `input-filename` fields are used for
the temperature module, we evaluated the following path:
```
[hwmon-path-abs] / [gap] / [input-filename]
```
where `gap` is the first file or directory in the `hwmon-path-abs`
directory. This usually works but it doesn't seem to work for NVME or
WiFi temperature sensors. For those cases, there are a bunch of other
files in the `hwmon-path-abs` directory. In the bad case, the first
selected file is not the one with the prefix `hwmon` and we end up
checking the wrong location for the `input-filename`.
Change description
------------------
We are simply going through the `hwmon-path-abs` directory and searching
for the first file/directory that begins with `hwmon`.
Test case
---------
I tested this on a AMD based Framework 13 laptop.
