Powertop recently started reporting "glob returned GLOB_ABORTED"

Hi folks,

I'm running powertop from git master on my Toshiba Chromebook (Intel Celeron N2840) using Crouton to provide an Ubuntu 14.04 chroot. Probably not a common configuration. :-)

Anyway on startup it has recently starting reporting "glob returned GLOB_ABORTED", thus:

RAPL device for cpu 0
RAPL device for cpu 0
RAPL device for cpu 0
Devfreq not enabled
glob returned GLOB_ABORTED

Kernel is 3.10.18 and this ChromeOS does provide the configs.ko kernel module (not loaded by default) so I can provide the kernel config if it's useful.

All the best,
Chris
