PCI/DPC: Make RP PIO log size check more generic
In dpc_probe(), we set dpc->rp_log_size to zero if we think the hardware reports an invalid size. In this case, we could have dpc->rp_extensions set but dpc->rp_log_size == 0, and we should print the basic RP PIO registers but not the variable-size portion. We already checked for dpc->rp_log_size < 4 above, so this patch is just for consistency of style. No functional change intended. Signed-off-by:Bjorn Helgaas <bhelgaas@google.com> Reviewed-by:
