Gabor Juhos 621979b49f kernel: yaffs: use new_sync_{read,write} for 3.18+ 
Using the do_sync_{read,write} functions in conjunction
with the generic_file_{read,write}_iter causes a kernel
panic like this:

  root@OpenWrt:/# mount -t yaffs /dev/mtdblock5 /mnt
  [ 2884.110000] yaffs: dev is 32505861 name is "mtdblock5" rw
