[2.6 patch] drivers/char/vt*: possible cleanups

[2.6 patch] drivers/char/vt*: possible cleanups

[Adrian Bunk]

This patch contains the following possible cleanups:
- make needlessly gloval code static
- vt_ioctl.c: removed the global variable keyboard_type since noone
              did actually set it to any other value

Signed-off-by: Adrian Bunk <bunk@stusta.de>
