Subject: [PATCH 0/2] can: usb: remove pointers to struct usb_interface in device's priv structures

The gs_can and ucan drivers keep a pointer to struct usb_interface in
their private structure. This is not needed. For gs_can the only use
is to retrieve struct usb_device, which is already available in
gs_usb::udev. For ucan, the field is set but never used.

Remove the struct usb_interface fields and clean up.

Vincent Mailhol (2):
  can: ucan: remove unused ucan_priv::intf
  can: gs_usb: remove gs_can::iface
