+Subject: drm/i915: Do a better job at disabling primary plane in the noatomic
+ case.
+
+When disable_noatomic is called plane_mask is not correct yet, and
+plane_state->visible = true is left as true after disabling the primary
+plane.
+
+Other planes are already disabled as part of crtc sanitization, only the
+primary is left active. But the plane_mask is not updated here. It gets
+updated during fb takeover in modeset_gem_init, or set to the new value
+on resume.
+
+This means that to disable the primary plane 1 << drm_plane_index(primary)
+needs to be used.
+
+Afterwards because the crtc is no longer active it's forbidden to keep
+plane_state->visible set, or a WARN_ON in
+intel_plane_atomic_calc_changes triggers. There are other code points
+that rely on accurate plane_state->visible too, so make sure the bool is
+cleared.
+
+The other planes are already disabled in intel_sanitize_crtc, so they
+don't have to be handled here.
