Title:
  "unknown op" error on running powertop --auto-tune

Status in powertop:
  New
Status in powertop package in Ubuntu:
  Confirmed
Status in powertop package in ALT Linux:
  Unknown
Status in powertop package in openSUSE:
  Fix Released

Bug description:
  powertop reports an unknown op error. I cannot claim that it's not
  functioning normally, otherwise.  Running it looks like this:

  $ sudo powertop --auto-tune
  Loaded 750 prior measurements
  RAPL device for cpu 0
  RAPL Using PowerCap Sysfs : Domain Mask f
  RAPL device for cpu 0
  RAPL Using PowerCap Sysfs : Domain Mask f
  RAPL device for cpu 0
  RAPL Using PowerCap Sysfs : Domain Mask f
  Devfreq not enabled
    unknown op '{'
  Leaving PowerTOP

  
  I don't see the error without --auto-tune.
