Subject: [PATCH 3.13 004/151] [3.13-stable] Revert "PCI: Enable INTx in pci_reenable_device() only when MSI/MSI-X not enabled"

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

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

From: Kamal Mostafa <kamal@...onical.com>

This reverts commit 16d36cdf2bd2b8e821ea1286dd3e8b2d657e6b3c.

... which was applied to 3.13-stable twice, first as:
        bb7048ea362773c2b53ee410a69ff60a029c71ef
and then again as:
        16d36cdf2bd2b8e821ea1286dd3e8b2d657e6b3c

This revert relates only to 3.13-stable, and the fix itself remains in 3.13.
