clang static analysis reports this problem:
rcutorture.c:1999:2: warning: Called function pointer
is null (null dereference)
cur_ops->sync(); /* Later readers see above write. */
^~~~~~~~~~~~~~~
This is a false positive triggered by an earlier, later ignored
NULL check of sync() op. By inspection of the rcu_torture_ops,
the sync() op is never uninitialized. So this earlier check is
not needed.
