Subject: [PATCH 9/9] drm/i915/gen9: fail the modeset instead of WARNing on unsuported config
Date: Tue, 13 Sep 2016 21:38:22 -0300	[thread overview]
Message-ID: <1473813502-16844-10-git-send-email-paulo.r.zanoni@intel.com> (raw)
In-Reply-To: <1473813502-16844-1-git-send-email-paulo.r.zanoni@intel.com>

Now that this code is part of the compute stage we can return -EINVAL
to prevent the modeset instead of giving a WARN and trying anyway.
