SRU Justification

Impact:

Azure kernels based on v6.5 and v6.8 fail Hyper-v hibernation.

Fix:

commit 5abffb66d12bcac84bf7b66389c571b8bb6e82bd drm: Check output polling initialized before disabling
commit 048a36d8a6085bbd8ab9e5794b713b92ac986450 drm: Check polling initialized before enabling in drm_helper_probe_single_connector_modes

Regression potential:

Hibernation could continue to fail, especially on older hyper-v releases.

Other Info:

SF: #00384521
