[media] jeilinj: fix return of the response code
drivers/media/usb/gspca/jeilinj.c: In function 'jlj_read1':
drivers/media/usb/gspca/jeilinj.c:117:66: warning: parameter 'response' set but not used [-Wunused-but-set-parameter]
The code still doesn't make much sense, as response is never tested
there.
