    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.
