In the Linux kernel, the following vulnerability has been resolved: i915/perf: Fix NULL deref bugs with drm_dbg() calls When i915 perf interface is not available dereferencing it will lead to
NULL dereferences. As returning -ENOTSUPP is pretty clear return when perf interface is not
available. [tursulin: added stable tag]
