    kernel-driver-development-debugging: adjust explanation about dynamic debug
    Some people where confused about the behavior of
    DEBUG/CONFIG_DYNAMIC_DEBUG: it wasn't clear to them that it's only
    when neither DEBUG nor CONFIG_DYNAMIC_DEBUG are used that the messages
    are not compiled in. I.e, they thought they needed both the debugging
    messages to be enabled.
    Let's reword a bit the explanation in an attempt to clarify that.

     \item Very powerful feature to only get the debug messages you're
       interested in.
-  \item When \code{DEBUG} is not defined and
-    \code{CONFIG_DYNAMIC_DEBUG} is not enabled, these messages are not
-    compiled in.
+  \item When neither \code{DEBUG} nor \code{CONFIG_DYNAMIC_DEBUG} are
