Subject: [Intel-gfx] [PATCH v2 2/7] drm/i915: Remove dead signal level debugs
Date: Thu, 18 Mar 2021 18:10:10 +0200	[thread overview]
Message-ID: <20210318161015.22070-3-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20210318161015.22070-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

If we ever get here with bogus signal levels we've messed
up somewhere earlier. Just use MISSIN_CASE().
