[PATCH][2.4.29-pre1] proc_tty.c warning fix

[Mikael Pettersson]

The /proc/tty/driver/serial vulnerability fix in 2.4.29-pre1
calls a function without a prototype in scope, resulting in:

proc_tty.c: In function `proc_tty_init':
proc_tty.c:183: warning: implicit declaration of function `proc_mkdir_mode'
proc_tty.c:183: warning: assignment makes pointer from integer without a cast

Fixed by the trivial patch below.
