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
