For _IO() ioctls, addr is a pointer to uap->data which is a caddr_t. When the caddr_t stores an int, dereferencing addr as an (int *) results in truncation on little-endian 64-bit systems and corruption (owing to extracting top bits) on big-endian 64-bit systems. In practice the value of chan was probably always zero on systems of the latter type as all such FreeBSD platforms use a register-based calling convention.
