Subject: [PATCH] PCI: dwc/meson: do not fail on wait linkup timeout
Date:   Mon, 21 Sep 2020 09:49:53 +0200

When establish link timeouts, probe fails but the error is unrelated since
the PCIe controller has been probed succesfully.

Align with most of the other dw-pcie drivers and ignore return of
dw_pcie_wait_for_link() in the host_init callback.
