drm/i915: add MISSING_CASE to a few port/aux power domain helpers (8e695444) · Commits · 戴 / test

MISSING_CASE() would have been useful to track down a recent problem in intel_display_port_aux_power_domain(), so add it there and a few related helpers. This was also suggested by Ville in his review of the latest DMC/DC changes, we forgot to address that. Reviewed-by:
