There are couple of scenario's as below:
- SystemSuspend-unplug-SystemResume
- VTLeave-unplug-VTEnter
During the above scenarios, though unplug uevent is triggered after resume/VTEnter by kernel, it wont reach modesetting driver (could be that X is not Master). To fix this, invoking a function to update the kms state during resume/VTEnter path.
Also the patch skips the modesetting error handling for missing and disconnected connectors in resume/VTEnter path. This is choosen to restore the older configuration as much as possible so as to support older kernel implementation which can restore once cables are plugged back.
