Subject: [PATCH V4 03/11] powerpc/pci: remove PCI devices in reverse order
Date: Fri, 15 May 2015 13:46:18 +0800 [thread overview]
Message-ID: <1431668786-30371-4-git-send-email-weiyang@linux.vnet.ibm.com> (raw)
In-Reply-To: <1431668786-30371-1-git-send-email-weiyang@linux.vnet.ibm.com>
As commit ac205b7b ("PCI: make sriov work with hotplug remove") indicates,
when removing PCI devices on a bus which has VFs, we need to remove them
in the reverse order.
This patch applies this pattern to the hotplug removal code for the powerpc
arch.
