$ make check-dup06
CHECK testcases/kernel/syscalls/dup/dup06.c
dup06.c:28: ERROR: return is not a function, parentheses are not required
dup06.c:53: ERROR: do not use assignment in if condition
dup06.c:56: WARNING: braces {} are not necessary for any arm of this statement

Therefore I'm going to merge with following change (+ please let me know if you
want to add your copyright).

Kind regards,
Petr
