The above was patch [2/5] in this series: https://lore.kernel.org/r/20250116-pci-pwrctrl-slot-v3-0-827473c8fbf4@xxxxxxxxxx/ ... so I think the preceding patch [1/5] is a prerequisite and would need to be cherry-picked as well. Upstream commit id is: 957f40d039a98d630146f74f94b3f60a40a449e4 That said, I'm not sure this is really a fix that merits backporting to stable. Mani may have more comments whether it makes sense. Thanks, Lukas
