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
Yes, thanks for spotting it Lukas, appreciated!
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.
Both this commit and the one corresponding to patch 1/5 are not bug fixes that
warrants backporting. So please drop this one from the queue.
I'll drop it, thanks!
