Subject[042/111] drm/i915: Use RSEN instead of HTPLG for tfp410 monitor detection.
2.6.32-stable review patch.  If anyone has any objections, please let us know.


From: Dave Müller <>

commit f458823b864c6def488f951a79986fa205aba4f1 upstream.

Presence detection of a digital monitor seems not to be reliable using
the HTPLG bit.
