Too late.  I fixed it last night and just checked it in.
The problem was that the "IO" and "CTRL" strings get
passed in as p_fixd->patch_args[1] and the code was indexing
with zero  :-(.  Also, after focusing on the code for too
long, my itchy fingers rewrote it to use a regex to parse
the #define-s.  This also fixed a little problem in that
this:

  #ifndef IO_QUOTES_DEF_CHECK
  #define BSD43__IOWR(n, x) (('n'<<8)+x)
  #endif  /* IO_QUOTES_DEF_CHECK */

was not patched into:

  #ifndef IO_QUOTES_DEF_CHECK
  #define BSD43__IOWR(n, x) ((n<<8)+x)
  #endif  /* IO_QUOTES_DEF_CHECK */
