Hi,

Here's a small patch that fixes automatic testing. I needed it to
review Paul's patch.

In addition to the patch that will follow in a response to
this mail, here's an URL to the see the patch in a web interface:
https://git.replicant.us/contrib/GNUtoo/hardware_replicant_libsamsung-ril/commit/?id=2dd9f229c88cb9fcd9257429bbfdee63e90db08e

And here's how to get it in a git repository:
