Subject: [PATCH 06/25] drm/i915: show unknown sdvox registers on hdmi init
Date: Wed, 9 May 2012 15:37:13 -0300 [thread overview]
Message-ID: <1336588652-702-7-git-send-email-eugeni.dodonov@intel.com> (raw)
In-Reply-To: <1336588652-702-1-git-send-email-eugeni.dodonov@intel.com>
This will throw a BUG() message when an unknown sdvox register is
given to intel_hdmi_init. When this happens, things could going to be pretty
much broken afterwards, so we better detect this as soon as possible.
