If anyone has any objections, please let me know. ------------------ From: Moiz Sonasath 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. [ balbi@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.
