[PATCH 2/2] [PATCH] removed unused var real_tty on n_tty_ioctl()

[Alan Cox]

From: Gustavo Fernando Padovan <gustavo@xxxxxxxxxxxxxxxxx>

Hello,

I noted that the 'struct tty_struct *real_tty' is not used in this
function, so I removed the code about 'real_tty'. This little change
is on kernel 2.6.25.4, but aplies on 2.6.24 or greater.
