[PATCHv4 19/28] PCI: mobiveil: continue to initialize the host upon no PCIe link
From: Z.q. Hou
Date: Mon Mar 11 2019 - 05:32:52 EST
From: Hou Zhiqiang <Zhiqiang.Hou@xxxxxxx>
Sometimes there is not a PCIe Endpoint in the PCIe slot, so do
not exit when the PCIe link is not up. And degrade the print
level of link up info.
