[Pali <pali.rohar@xxxxxxxxx>]

I tested mei.ko and mei-me.ko drivers from linux-image-3.13.0-51-generic
source with these two additional patches:

http://kernel.ubuntu.com/git/kamal/ubuntu-
trusty.git/commit/?h=pali-1450813&id=cce32088947917cb93520b9dffc0fd4bb0b21ade

http://kernel.ubuntu.com/git/kamal/ubuntu-
trusty.git/commit/?h=pali-1450813&id=845a0dc3427014d8ff74a34f90120be88e98760c

And after that mei.ko and mei-me.ko initialized without any error.

Bug description:
  After upgrading linux-image-3.13.0-49-generic to linux-
  image-3.13.0-51-generic I started getting this error message in dmesg:

  [ 6.352555] mei_me 0000:00:16.0: irq 47 for MSI/MSI-X
  [ 6.355708] mei_me 0000:00:16.0: version message write failed: ret = -5
  [ 6.355712] mei_me 0000:00:16.0: hbm_start failed ret = -5
  [ 6.355714] mei_me 0000:00:16.0: reset failed
  [ 6.355716] mei_me 0000:00:16.0: link layer initialization failed.
  [ 6.355717] mei_me 0000:00:16.0: init hw failure.
  [ 6.355880] mei_me 0000:00:16.0: initialization failed.

  Downgrading back to linux-image-3.13.0-49-generic fixed this problem.
  So this is regression for version 3.13.0-51.
