Is it so difficult to add a couple of lines of description ?

There are lots of examples in previous patches.

     hwmon: (k10temp) add support for cyan skillfish

     Add support for Cyan Skillfish (AMD Family 17h Model 47h),
     which appear to be Zen 2 based APU.


     hwmon: (k10temp) Add support for AMD Family 19h Model 8h

     Add support for AMD Family 19h Model 8h CPUs, which appear to
     be the Zen 3 based AMD Threadripper 5000WX series (Chagall).


     hwmon: (k10temp) Add thermal support for AMD Family 1Ah-based models

     Add thermal info support for AMD Family 1Ah-based models. Support is
     provided on a per-socket granularity.


     hwmon: (k10temp): Add support for new family 17h and 19h models

     Add the support for CCD offsets used on family 17h models A0h-AFh,
     and family 19h models 60h-7Fh.

Even

     hwmon: (k10temp) Add PCI ID for family 19, model 78h

     Enable k10temp on this system.

is better than nothing.

Ok, ok, no problem, I'll do it myself, and add a note saying that this is
Zen 5 based Granite Ridge. If and when I find the time to do it.
