From a4b21b858b56d728021ad72ad7c1322d8772b2a6 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 22 May 2020 17:48:25 -0600 Subject: [PATCH] PCI: versatile: Use pci_host_probe() to register host The versatile host driver does the same host registration and bus scanning calls as pci_host_probe, so let's use it instead.
