Revision a6093ad7fc4962099d2d723bcca72f8175b58c82 authored by Leonard Crestez on 31 January 2019, 20:59:50 UTC, committed by Bjorn Helgaas on 31 January 2019, 20:59:50 UTC
On chips without a separate power domain for PCI (such as 6q/6qp) the
imx6_pcie_attach_pd() function incorrectly returns an error.

Fix by returning 0 if dev_pm_domain_attach_by_name() does not find
anything.
