From 15ccbf042ddda877cde23e9b0d5d3f5256e62c33 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Wed, 20 Mar 2019 15:09:44 +0530 Subject: {northbridge, soc, southbridge}/intel: Make use of generic set_subsystem() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch removes all local definitions of sub_system functions and make use of common generic pci_dev_set_subsystem() from PCI bridge and Cardbus devices as well.
