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.

Other Info:

SF: #00384521
