[BusyBox] [PATCH] size optimisation for chvt.c

[Tito]

Hi to all,
this patch reduces size of chvt.o from:
   text    data     bss     dec     hex filename
    141       0       0        141     8d  chvt_orig.o
-rw-r--r--    1 root     root         1280 Jan 11 19:20 chvt_orig.o

to:

   text    data     bss     dec     hex filename
    138       0       0       138      8a  chvt.o
-rw-r--r--    1 root     root         1268 Jan 13 15:27 chvt.o

Please apply.
Ciao,
Tito
