[PATCH 3.2 079/185] PCI: Remove duplicate pci_disable_device()from pcie_portdrv_remove()

[Ben Hutchings]

3.2.54-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Yinghai Lu <yinghai@xxxxxxxxxx>

commit e7cc5cf74544d97d7b69e2701595037474db1f96 upstream.

The pcie_portdrv .probe() method calls pci_enable_device() once, in
pcie_port_device_register(), but the .remove() method calls
pci_disable_device() twice, in pcie_port_device_remove() and in
pcie_portdrv_remove().

That causes a "disabling already-disabled device" warning when removing a
PCIe port device.  This happens all the time when removing Thunderbolt
devices, but is also easy to reproduce with, e.g.,
"echo 0000:00:1c.3 > /sys/bus/pci/drivers/pcieport/unbind"

This patch removes the disable from pcie_portdrv_remove().
