Subject: [PATCH 15/27] powerpc/pseries: Move controller ops from ppc_md to controller_ops
Date: Wed, 25 Mar 2015 16:35:49 +1100	[thread overview]
Message-ID: <1427261761-22952-16-git-send-email-dja@axtens.net> (raw)
In-Reply-To: <1427261761-22952-1-git-send-email-dja@axtens.net>

This moves the pSeries platform to use the pci_controller_ops structure,
rather than ppc_md for PCI controller operations.
