drivers/usb/misc/sisusbvga/sisusb.c: In function usb_sisusb_init:
drivers/usb/misc/sisusbvga/sisusb.c:3321: warning: unused variable sisusb
drivers/usb/misc/sisusbvga/sisusb.c:3320: warning: unused variable retval

are trivially solved by getting rid of the unused variables.

drivers/usb/misc/sisusbvga/sisusb.c: In function sisusb_open
drivers/usb/misc/sisusbvga/sisusb.c:2444: warning: sisusb is used uninitialized in this function

is a genuine bug (which will cause oops). We cannot use "sisusb" in
error path for (!interface), because sisusb will itself be derived
from "interface" later.
