Sparse complains:

[dedekind@...ron l2-mtd-2.6 (master)]$ make C=1
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CHECK   drivers/mtd/devices/docg3.c
drivers/mtd/devices/docg3.h:217:21: error: dubious one-bit signed bitfield

And indeed:

        int device_id:4;
        int if_cfg:1;

should be unsigned int bit-fields, not signed.
