[PATCH 4.1 16/84] drm/dp-mst: Remove debug WARN_ON

From: Greg Kroah-Hartman
Date: Fri Aug 14 2015 - 14:23:30 EST


4.1-stable review patch. If anyone has any objections, please let me know.

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

From: Daniel Vetter <daniel.vetter@xxxxxxxx>

commit 42639ba554655c280ae6cb72df0522b1201f2961 upstream.

Apparently been in there since forever and fairly easy to hit when
hotplugging really fast. I can do that since my mst hub has a manual
button to flick the hpd line for reprobing. The resulting WARNING spam
isn't pretty.
