More importantly, it doesn't really create (i.e. allocate) a handle. It allocates a native_handle_t, copies it to a struct gralloc_handle_t on the stack and returns the struct (not a ptr). So the caller still has to allocate a struct gralloc_handle_t to hold the returned struct. Rework gralloc_handle_create() to allocate a new handle and return the pointer to the allocated handle. Callers should free the handle with native_handle_close() and native_handle_delete().
