Azure: Fix hibernation failure

[Tim Gardner]

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

This bug is awaiting verification that the linux-azure/6.5.0-1022.23 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-mantic-linux-azure' to 'verification-done-mantic-linux-azure'. If the problem still exists, change the tag 'verification-needed-mantic-linux-azure' to 'verification-failed-mantic-linux-azure'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
