usbip: vhci-hcd: Rename function names to reflect their struct names
These helper function names are renamed to have their full struct names to avoid confusion: - hcd_to_vhci() -> hcd_to_vhci_hcd() - vhci_to_hcd() -> vhci_hcd_to_hcd() - vdev_to_vhci() -> vdev_to_vhci_hcd() Signed-off-by: Yuyang Du <yuyang.du@intel.com> Acked-by: Shuah Khan <shuahkh@osg.samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
