In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Grab intel_display from the encoder to avoid potential oopsies
Grab the intel_display from 'encoder' rather than 'state'
in the encoder hooks to avoid the massive footgun that is
intel_sanitize_encoder(), which passes NULL as the 'state'
argument to encoder .disable() and .post_disable().
TODO: figure out how to actually fix intel_sanitize_encoder()...
