Subject: [PATCH 3.18 91/93] Revert "PCI/MSI: Stop disabling MSI/MSI-X in pci_device_shutdown()"

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

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

From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>

This reverts commit 058645e2f0647c85f2bfd577771546d198739fd2 which was
commit fda78d7a0ead144f4b2cdb582dcba47911f4952c upstream.

The dependancy tree is just too messy here, just drop it from this
kernel as it's not really needed here.
