[Intel-gfx] [PATCH 1/5] drm/i915: Ensure crtc_state backpointer is initialized

[Matt Roper]

From: Matt Roper <matt at mattrope.com>

Since our legacy modeset paths directly kzalloc CRTC state objects at
the moment rather than calling intel_crtc_duplicate_state(), we need to
manually ensure the ->crtc backpointer is always initialized.
