If anyone has any objections, please let me know. ------------------ From: Daniel Vetter 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.
