   4 Subject: [PATCH] vpu_wrapper: fix tests of return value from IOGetVirtMem
   5
   6 IOGetVirtMem() returns a pointer or specifically -1 (MAP_FAILED)
   7 in the case of failure.
   8
   9 This problem is being discussed upstream at
  10 https://lists.yoctoproject.org/pipermail/meta-freescale/2014-June/008993.html.
