We get 3 warnings when build kernel with W=1:
drivers/isdn/hardware/mISDN/avmfritz.c:288:1: warning: no previous prototype
for 'write_ctrl' [-Wmissing-prototypes]
drivers/isdn/hardware/mISDN/avmfritz.c:745:1: warning: no previous prototype
for 'clear_pending_hdlc_ints' [-Wmissing-prototypes]
drivers/isdn/hardware/mISDN/avmfritz.c:966:1: warning: no previous prototype
for 'setup_fritz' [-Wmissing-prototypes]
In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.
