Azure: Fix hibernation failure

[Tim Gardner]

SRU Justification

Impact:

Microsoft has reported hibernation failures with Azure based kernels. Mantic and Noble already have the fix patches via stable.

Fix:

drm: Check output polling initialized before disabling
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.9-rc5&id=5abffb66d12bcac84bf7b66389c571b8bb6e82bd

drm: Check polling initialized before enabling in drm_helper_probe_single_connector_modes
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.9-rc5&id=048a36d8a6085bbd8ab9e5794b713b92ac986450

Regression Potential:

Though these 2 patches are backports to stable (and thus of low regression potential), hibernation could continue to fail.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-azure/5.15.0-1068.77 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-jammy-linux-azure' to 'verification-done-jammy-linux-azure'. If the problem still exists, change the tag 'verification-needed-jammy-linux-azure' to 'verification-failed-jammy-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.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
