So, should I split it into two different patches? One patch for the fix
and other for the extra documentation?

Finally, in the two warnings related to "please write a paragraph that
describes the config symbol fully" the extra documentation that fixes
it. Other fixes, are related to the coding-style.rst however checkpatch
does not complain about them.
