This looks great!

Applied to pci/vpd for v5.15, thanks!

I tweaked 2/6 to test for func0_dev being NULL in pci_read_vpd()
instead of pci_vpd_read().  Could go either way, but it's really only
relevant for the PCI_DEV_FLAGS_VPD_REF_F0 case, which is now all in
pci_read_vpd().  For the non-PCI_DEV_FLAGS_VPD_REF_F0 case, we've
already dereference dev->dev_flags, so "dev" can never be NULL in
pci_vpd_read().
