Applied.  You've got a funny convention in your commit messages, though,
where you copy the first line of the commit message into the second
paragraph.  I end up deleting that most of the time when I notice it.
The second paragraph should be additional details to the summary for
understanding the change.  Here's what I ended up putting on
this patch:

drm/i915: Add 30ms delay to make SDVO TV detection reliable.

Without this, on some boots the TV wouldn't be detected.  Testing
showed 15ms to be insufficient.
