Subject: [PATCH 0/2] drm/msm/dp: fix runtime PM leaks on hotplug

As I've reported elsewhere, I've been hitting runtime PM usage count
leaks when investigated a DisplayPort hotplug regression on the Lenovo
ThinkPad X13s. [1]

This series addresses two obvious leaks on disconnect and on connect
failures, respectively.
