Subject: [PATCH V3 3/9] powerpc/pci: remove PCI devices in reverse order
Date: Mon,  4 May 2015 15:07:32 +0800	[thread overview]
Message-ID: <1430723258-21299-4-git-send-email-weiyang@linux.vnet.ibm.com> (raw)
In-Reply-To: <1430723258-21299-1-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.
