Fix this warning:

  drivers/isdn/mISDN/timerdev.c:264:11: warning: incorrect type in initializer (incompatible argument 2 (different address spaces))
  drivers/isdn/mISDN/timerdev.c:264:11:    expected int ( *read )( ... )
  drivers/isdn/mISDN/timerdev.c:264:11:    got int ( static [toplevel] *<noident> )( ... )
