3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Moiz Sonasath <m-sonas...@ti.com>
commit 296365781903226a3fb8758901eaeec09d2798e4 upstream.
For non PCI-based stacks, this function call
usb_disable_xhci_ports(to_pci_dev(hcd->self.controller));
made from xhci_shutdown is not applicable.
Ideally, we wouldn't have any PCI-specific code on
a generic driver such as the xHCI stack, but it looks
like we should just stub usb_disable_xhci_ports() out
for non-PCI devices.
[ ba...@ti.com: slight improvement to commit log ]
This patch should be backported to kernels as old as 3.0, since the
commit it fixes (e95829f474f0db3a4d940cae1423783edd966027 "xhci: Switch
PPT ports to EHCI on shutdown.") was marked for stable.
