[igt-dev] [PATCH v3 3/3] core_getversion: Test for desired device

[Rob Clark <robdclark@gmail.com>]

From: Rob Clark <robdclark@chromium.org>

We discovered in drm/ci that if the drm device fails to probe, all the
tests come back as "Skip" and the job is considered successful. Fix
the getversion test to fail if there is no drm device or if the drm
device does not match the expected device as specified by the optional
IGT_REQUIRED_DRIVER environment variable.
