Odd, you might need to upgrade the version of sparse you have.  My
output looks like:

$ make M=drivers/staging/xillybus/ C=1
  LD      drivers/staging/xillybus//built-in.o
  CHECK   drivers/staging/xillybus//xillybus_core.c
drivers/staging/xillybus//xillybus_core.c:76:25: warning: symbol 'xillybus_wq' was not declared. Should it be static?
drivers/staging/xillybus//xillybus_core.c:175:57: warning: incorrect type in argument 2 (different address spaces)

and goes on for a few screens.

$ sparse --version
0.4.4

Try a newer version and see if that fixes things.
