From 97c5372aeb5b43ab9d3f3db08652de8e8988b226 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 22 May 2020 17:48:26 -0600 Subject: [PATCH] PCI: xgene: Use pci_host_probe() to register host The xgene host driver does the same host registration and bus scanning calls as pci_host_probe, so let's use it instead.
