From Documentation/core-api/printk-formats.rst:
kobjects --------
::
%pOF[fnpPcCF]
For printing kobject based structs (device nodes). Default behaviour is equivalent to %pOFf.
- f - device node full_name - n - device node name - p - device node phandle - P - device node path spec (name + @unit) - F - device node flags - c - major compatible string - C - full compatible string
