   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit

   9 We have generic place & helpers for storing platform driver data so
  10 there is no reason for using custom priv pointer.
  11
  12 This allows cleaning up struct bcma_sflash from unneeded fields.
