Subject: [PATCH] drm/i915/perf: destroy stream on sample_flags mismatch
Date: Mon, 27 Mar 2017 21:34:59 +0100	[thread overview]
Message-ID: <20170327203459.18398-1-matthew.auld@intel.com> (raw)

If we were to ever encounter a sample_flags mismatch we need to ensure
we destroy the stream when we bail.

Fixes: d79651522e89 ("drm/i915: Enable i915 perf stream for Haswell OA unit")
