Subject: [PATCH v2 10/13] drm/i915: Use crtc->state in intel_fbdev_init_bios
Date: Thu,  4 Oct 2018 11:46:01 +0200	[thread overview]
Message-ID: <20181004094604.2646-11-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20181004094604.2646-1-maarten.lankhorst@linux.intel.com>

fbdev init shouldn't race with userspace since it's called from
intel_modeset_init, so it's safe to dereference crtc->state and
assume nothing changed yet.

At least not more harmful than crtc->config.
