[19/55] drm/i915/tv: Remember the detected TV type

From: Greg KH
Date: Fri Apr 29 2011 - 15:07:04 EST


2.6.38-stable review patch. If anyone has any objections, please let us know.

------------------

From: Mathew McKernan <matmckernan@xxxxxxxxxxxxxx>

commit d5627663f2088fa4be447fdcfd52bcb233448d85 upstream.

During detect() we would probe the connection bits to determine if
there was a TV attached, and what video input type (Component, S-Video,
Composite, etc) to use. However, we promptly discarded this vital bit of
information and never propagated it to where it was used to determine
the correct modes and setup the control registers. Fix it!

This fixes a regression from 7b334fcb45b757ffb093696ca3de1b0c8b4a33f1.
