[Libdlo] [PATCH] Fix device crash

[Bernie Thompson]

Thanks for taking the time to submit a patch.  It has been applied to
the libdlo git repository
(http://cgit.freedesktop.org/libdlo/commit/?id=8b462793d5137f51c7e30ccc0de3291d8363e6ab).

Tested working on an ASUS VW223B device (which didn't have the problem
you reported, however).  Is the same device working or not with
displaylink-mod?

Thanks,
Bernie
