smp_read_barrier_depends() to READ_ONCE()"), it still limps on in the
Linux memory model with the sinister hope of attracting innocent new
users so that it becomes impossible to remove altogether.

[PATCH v2 0/4] drm/dp_mst: Fix regressions from new atomic VCPI helpers
This fixes the extra issues I discovered upstream after the introduction

This time around, we use a slightly different but much less complicated
approach for fixing said issues.
