[PATCHv5 17/20] PCI: mobiveil: Complete initialization of host even if no PCIe link

From: Z.q. Hou
Date: Fri Apr 12 2019 - 04:37:01 EST


From: Hou Zhiqiang <Zhiqiang.Hou@xxxxxxx>

Sometimes there is not a PCIe Endpoint stalled in the slot,
so do not exit when the PCIe link is not up. And degrade the
print level of link up info.
