    drm/i915/pmu: Initialise our dynamic sysfs attributes for use with lockdep
    
    As we kmalloc our dynamic sysfs attributes, we have to give them an
    external static lock_class_key for them to use with lockdep.
    
    Fixes: 109ec558370f ("drm/i915/pmu: Only enumerate available counters in sysfs")

Fix integrated into CI_DRM_3622, the issue has not been reproduced, thanz Chris.

Started again on CI_DRM_3673 KBL-shards:

It appear to be a bit flip/floppy so eventhough CI_DRM_3675 I can say that it is fixed.

No, this is a cascade failure from live_hangcheck on kbl. See the stack page overflow double fault.

Agreed, keep forgetting that selftest shard don't have randomized test ordering. igt@drv_selftest@live_hangcheck is covered by softdog bug 104262. But it has been flip/flopping pass/fail/incomplete for quite some time on KBL-shards. All fails seem to correspond to issues on drm_mm tests.

Updating dup to link to kbl-only stack page overflow bug.
