Pull tracing cleanup from Steven Rostedt:
 "Remove second argument of __assign_str()

  The __assign_str() macro logic of the TRACE_EVENT() macro was
  optimized so that it no longer needs the second argument. The
  __assign_str() is always matched with __string() field that takes a
  field name and the source for that field:

    __string(field, source)

  The TRACE_EVENT() macro logic will save off the source value and then
  use that value to copy into the ring buffer via the __assign_str().

  Before commit c1fa617caeb0 ("tracing: Rework __assign_str() and
  __string() to not duplicate getting the string"), the __assign_str()
  needed the second argument which would perform the same logic as the
  __string() source parameter did. Not only would this add overhead, but
  it was error prone as if the __assign_str() source produced something
  different, it may not have allocated enough for the string in the ring
  buffer (as the __string() source was used to determine how much to
  allocate)

  Now that the __assign_str() just uses the same string that was used in
  __string() it no longer needs the source parameter. It can now be
  removed"
