From c63aed7334c21de8d626ff028ccad98cf5847a0e Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Fri, 22 May 2020 17:48:27 -0600 Subject: [PATCH] PCI: altera: Use pci_host_probe() to register host The altera host driver does the same host registration and bus scanning calls as pci_host_probe, so let's use it instead. The only difference is pci_assign_unassigned_bus_resources() was called instead of pci_bus_size_bridges() and pci_bus_assign_resources(). This should be the same.
