[PATCH] PCI: dwc: do not ignore link errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This fixes long boot delays of about 10 seconds.

I am working on a device powered by an TI am65 SoC where
we have a PCIe expansion slot. If there is no PCIe device
connected I see boot delays caused by pci_host_probe(..).
