There are some wrong usage of ATTRIBUTE_NONNULL, which may cause the compilation fail. The
ATTRIBUTE_NONNULL is the define of __attribute__((__nonnull__(m))), which declares that the
input pointer parameter of funciton should not be NULL. If we declare some input pointer
parameter of the function is ATTRIBUTE_NONNULL, the function should not redundancy check of
the pointer parameter. And the ATTRIBUTE_NONNULL can only be using to pointer.
