sparc64: vcc: Check for IS_ERR() instead of NULL
The tty_alloc_driver() function never returns NULL, it returns error pointers on error. Fixes: ce808b746325 ("sparc64: vcc: TTY driver initialization and cleanup") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
