Subject: tty: fix unused warning when TCGETX is not defined
X-Git-Tag: v2.6.31-rc1~309^2~5

tty: fix unused warning when TCGETX is not defined

If TCGETX is not defined, we end up with this warning:
drivers/char/tty_ioctl.c: In function ‘tty_mode_ioctl’:
drivers/char/tty_ioctl.c:950: warning: unused variable ‘ktermx’

Since the variable is only used in one case statement, push it down to
the local case scope.
