This is a note to let you know that I have just added a patch titled
Subject: [PATCH 11/21] drm/i915/sdvo: Always add a 30ms delay to make SDVO
TV detection reliable
to the drm-next branch of the 2.6.32+drm33-longterm tree which can be found at
http://git.kernel.org/?p=linux/kernel/git/smb/linux-2.6.32.y-drm33.z.git;a=shortlog;h=refs/heads/drm-next

Subject: [PATCH 11/21] drm/i915/sdvo: Always add a 30ms delay to make SDVO TV
detection reliable
commit ba84cd1f2b5dd49bda9300c5a11373f7e14c3c66 upstream.
Commit d09c23de intended to add a 30ms delay to give the ADD time to
detect any TVs connected. However, it used the sdvo->is_tv flag to do so
which is dependent upon the previous detection result and not whether the
output supports TVs.
