usb_hcd_pci_remove - shutdown processing for PCI-based HCDs
void usb_hcd_pci_remove (struct pci_dev * dev);
dev USB Host Controller being removed
Reverses the effect of usb_hcd_pci_probe, first invoking the HCD’s stop method. It is always called from a thread context, normally ‘‘rmmod’’, ‘‘apmd’’, or something similar. Store this function in the HCD’s struct pci_driver as remove.
