Severity: grave
Hi,
Recently, Kodi has started segfaulting on startup, pointing to libcec3.
A backtrace reads:

It would seem libcec3 unconditionally assumes /sys/class/drm exists
(it does not on my system using the proprietary NVIDIA driver, since
that driver doesn't use drm), and then segfaults when it doesn't.
Could you please add a check for the NULL value?
