   4 Subject: [PATCH] rt2x00: Remove check for rf word 0
   5
   6 The only way rf_write() can be called with word 0 is
   7 when the user sends the wrong word index through debugfs.
   8 However the values which are send through debugfs are
   9 validated using the RF_BASE and RF_SIZE macro values,
  10 the most logical solution is to increase RF_BASE with 4
  11 and decrease RF_SIZE with 4 (RF_SIZE has always been
  12 1 word too big)
