For merging propably best we wait for the backmerge and the push these in through drm-misc-next-fixes. Well for drm-misc-next-fixes drm-misc maintainers need to roll the tree forward.

I'm quite new to drm so I'll withhold a reviewed-by tag and ask that someone else take a look at it too. Lyude, the original author, mentioned he should probably take a look again also since the patchset is a bit old. > For merging propably best we wait for the backmerge and the push > these in > through drm-misc-next-fixes. > > Well for drm-misc-next-fixes drm-misc maintainers need to roll the > tree > forward.

Updated and resending these patches from Lyude: https://lkml.org/lkml/2016/5/19/361 https://lkml.org/lkml/2016/5/19/360 As Lyude explains in patch 1/2, we can't rely on MST hubs to handle hotplugs during suspend. This patchset will check if any EDID's changed upon resume and reset the MST connections if they did. This resolves issues with monitors not being detected when hotplugging them during suspend.
