V4L/DVB (4275): The FE_SET_FRONTEND_TUNE_MODE ioctl always returns EOPNOTSUPP

Browse source 
When someone added the front-end ioctl FE_SET_FRONTEND_TUNE_MODE, they
forgot to set the return value to 0.  It always returns EOPNOTSUPP,
causing problems for programmers who actually check for error conditions.
