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
