removed unused var real_tty on n_tty_ioctl()
...
I noted that the 'struct tty_struct *real_tty' is not used in this
function, so I removed the code about 'real_tty'.

Add a bunch of cycle_kernel_lock() calls
...
All of the open() functions which don't need the BKL on their face may
still depend on its acquisition to serialize opens against driver
initialization. So make those functions acquire then release the BKL to be
on the safe side.
