zenpower3 and 6.16 kernel

[Dany-Wilde]

Could someone rewrite the module to ensure that it works properly with kernels 6.16 and above (more recent)?

If I have to do without it, I'll do without it.
But only if I really have to.
It doesn't suit me at all.
Zenpower meets a need.
Well, less and less since the AM5 platform came out, but still...

If someone could rewrite the module, that would be great.
For Zen3 (R9 5900X in my case) on kernel 6.16 and future versions...
That would be cool.

Thanks.
Respectfully,
Dany.
