From 49886cf4c4cd2ef77d0698c389199ad3e236f48e Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 28 Jan 2014 16:40:36 -0700 Subject: [PATCH] x86/PCI: Drop return value of pcibios_scan_root() Nobody really uses the return value of pcibios_scan_root() (one place uses it to control a printk, but the printk is not very useful). This converts pcibios_scan_root() to a void function. Signed-off-by: Bjorn Helgaas Acked-by: Rafael J.
