 Trace event fix of string verifier
 
 - The run time string verifier that checks all trace event formats
   as they are read from the tracing file to make sure that the %s
   pointers are not reading something that no longer exists, failed
   to account for %*.s where the length given is zero, and the string
   is NULL. It incorrectly flagged it as a null pointer dereference and
   gave a WARN_ON().

 "The run-time string verifier checks all trace event formats as
  they are read from the tracing file to make sure that the %s pointers
  are not reading something that no longer exists.

  However, it failed to account for the valid case of '%*.s' where the
  length given is zero, and the string is NULL. It incorrectly flagged
  it as a null pointer dereference and gave a WARN_ON()"
