We get 1 warning when build kernel with W=1:
drivers/isdn/hardware/mISDN/mISDNipac.c:117:1: warning: no previous prototype for 'isac_empty_fifo' [-Wmissing-prototypes]

In fact, this function is only used in the file in which it is declared
and don't need a declaration, but can be made static.
so this patch marks it 'static'.
