I've sent this patch so long ago, that I almost forgot that it is not
merged. Vikash, Bryan, anything pending from my side?

I've pointed out previously the fluster-tests repo, which I'm trying to
use to record test results on various platforms using the fluster suite.
The suite uses FFmpeg and GStreamer under the hood, which means that
major multimedia apps work with Venus and Iris. There are known failures
(sadly) and even more sadly there are known tests which can crash the
device (those, defined in -skip files).

For QCS6490, please try using the newer, Iris driver. It proved to be
more stable.
