With what is in tmp.perf-tools-next I'm getting:

I'm working on removing the vfs_getname code from 'perf trace' so those
will go away, probably there are patches fixing some of the other ones,
I'll try and look after those, but probably later today I'll push what I
have so that it gets exposure on linux-next.

I'm trying to repro the hwmon issue on tmp.perf-tools-next, with asan
root/non-root I get:
```
 11: Hwmon PMU                                                       :
11.1: Basic parsing test                                            : Ok
11.2: Parsing without PMU name                                      : Ok
11.3: Parsing with PMU name                                         : Ok
```
I'm trying more machines to try to get a reproduction.

Thanks,
Ian

So, I cleaned up everything, rebuilt and the problem persists on a
Fedora 40 lenovo x1 carbon, full verbose mode output at the end.

It also fails on a Raspberry Pi 3:

Hope this helps, will go AFK now, happy to try more stuff and will also
try to figure this out myself if you don't do it first.

Since this doesn't seem to be something related to the patches processed
this week I'll just push what we have to perf-tools-next so that it gets
tested on linux-next.
