Shutdown processing for pci-based hcds
void usb_hcd_pci_remove(struct pci_dev * dev);
dev
USB Host Controller being removed
!in_interrupt
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.
