   1 /*
   2
   3     Types and defines needed for RDS. This is included by
   4     saa6588.c and every driver (e.g. bttv-driver.c) that wants
   5     to use the saa6588 module.
   6
   7     Instead of having a separate rds.h, I'd prefer to include
   8     this stuff in one of the already existing files like tuner.h
