3.13.11-ckt26 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Daniel Vetter <[email protected]> commit 5677d67ae3949f09f57357241b88222d49b8c782 upstream. It's causing piles of issues since we've stopped forcing full detect cycles in the sysfs interfaces with commit c484f02d0f02fbbfc6decc945a69aae011041a27 Author: Chris Wilson <[email protected]> Date: Fri Mar 6 12:36:42 2015 +0000 drm: Lighten sysfs connector 'status' The original justification for this was that the hpd handlers could use the unknown state as a hint to force a full detection. But current i915 code isn't doing that any more, and no one else really uses reset on resume. So instead just keep the old state around.
