In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier.Please forgive my ignorance, but what is this format specifier do exactly? I cannot find anything listed in the printf specification matching this. Is this something newly introduced? LeoFrom Documentation/core-api/printk-formats.rst:
I was trying to find it in the standard c format specifier. :( Thanks a lot for the pointer.
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
