target/linux/rb532/patches-2.6.27/006-pata_rb532_cf_fix_prototype.patch

   1 Per definition, this function should return the number of bytes
   2 consumed. Also take care of the unlikely case when buflen is not a
   3 multiple of four; while transferring, the division cuts the remaining
   4 bytes, so alter the return value accordingly.
