I noted that in get_ep() in drivers/media/video/gspca/gspca.c
usb_set_interface() is not called for an ISOC endpoint with an
altsetting of 0. Is that ok?

get_ep() has changed in the last releases. Now, usb_set_interface() is
called on (gspca_dev->nbalt > 1), i.e when there is more than one alternate setting.
