Subject: [PATCH] drm/i915: Don't get hw state from DVO chip unless DVO is
 enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Certain DVO chips (ns2501 for example) don't like to be accessed unless
the PLL is running. Simply skip the DVO get_hw_state if the DVO port
is disabled.
