  [PATCH] drm/i915: Change WARN_ON(!wm_changed) to I915_STATE_WARN_ON() Lyude <cpaul@redhat.com> - 2016-02-22 20:30 +0100

#1339857 — [PATCH] drm/i915: Change WARN_ON(!wm_changed) to I915_STATE_WARN_ON()

These warnings still seem to be present with DP MST configurations. They
don't actually indicate any impending doom, so we may as well use
I915_STATE_WARN_ON() here to help quiet things down a little bit for
distro kernel users.
