I guess you might have already included this patch:
15becc2b56c6 ("PCI: hv: Add hv_pci_remove_slots() when we unload the
driver")
Unluckily it turns out it is buggy and just now I had to post a further patch
for it:
[PATCH] PCI: hv: Fix panic by calling hv_pci_remove_slots() earlier
( https://lkml.org/lkml/2019/8/1/1173)
Please consider including this further patch as well.
