Summary
drm: Check output polling initialized before disabling
Details

In the Linux kernel, the following vulnerability has been resolved:

drm: Check output polling initialized before disabling

In drmkmshelperpolldisable() check if output polling support is initialized before disabling polling. If not flag this as a warning. Additionally in drmmodeconfighelpersuspend() and drmmodeconfighelperresume() calls, that re the callers of these functions, avoid invoking them if polling is not initialized. For drivers like hyperv-drm, that do not initialize connector polling, if suspend is called without this check, it leads to suspend failure with following stack [ 770.719392] Freezing remaining freezable tasks ...
