[char-misc 0/4] mei: reset fix

[Tomas Winkler]

This series should address possible hiccup in
mei reset flow presenting itself as never ending   
repetition of error line.

unexpected reset: dev_state = RESETTING  

The patches make sure that stall watchdog doesn't jump in 
prior to its time; second the reset flow won't recuse,
and at last  it will allow no more than 3 consecutive resets
for misbehaving hardware.


Tomas Winkler (4):
  mei: do not run reset flow from the interrupt thread
  mei: use hbm idle state to prevent spurious resets
  mei: revamp mei reset state machine
  mei: limit the number of consecutive resets
