sorry for the noise - discussions about a similar "cleanup" in RCU
resulted Joe Perches <joe@...ches.com> clarifying the matter - this
explicit conversion makes static code checkers happy but is not
needed for gcc (or C for that mater) - see 
  http://lkml.org/lkml/2015/5/24/47
  and ISO/IEC 9899:1999 (c99) 6.8.6.4 subclause 3)
