Subject: [PATCH 8/8] drm/i915/dp: clear receiver_configured when link training fails
Date: Fri, 1 Jul 2011 15:22:58 -0700 [thread overview]
Message-ID: <1309558978-4704-9-git-send-email-jbarnes@virtuousgeek.org> (raw)
In-Reply-To: <1309558978-4704-1-git-send-email-jbarnes@virtuousgeek.org>
When link training or detection fails, set the receiver_configured flag
to false to reflect the current state.
