Yes, agreed.

But with this patch applied, make CC=clang W=1 tells me:

  CALL    scripts/checksyscalls.sh
  CC [M]  drivers/isdn/hardware/mISDN/hfcmulti.o
drivers/isdn/hardware/mISDN/hfcmulti.c:643:1: error: unused function 'cpld_read_reg' [-Werror,-Wunused-function]

So perhaps cpld_read_reg should be removed too?
