Subject: [PATCH 4.8 16/35] PCI: Export pcie_find_root_port
Date: Wed,  7 Dec 2016 08:08:32 +0100	[thread overview]
Message-ID: <20161207070723.359142240@linuxfoundation.org> (raw)
In-Reply-To: <20161207070722.410336250@linuxfoundation.org>

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Johannes Thumshirn <jthumshirn@suse.de>

commit e784930bd645e7df78c66e7872fec282b0620075 upstream.

Export pcie_find_root_port() so we can use it outside of PCIe-AER error
injection.
