-/*
- * Driver for Philips SAB3036 "CITAC" tuner control chip.
- *
- * Author: Phil Blundell <philb@gnu.org>
- *
- * The SAB3036 is just about different enough from the chips that
- * tuner.c copes with to make it not worth the effort to crowbar
- * the support into that file. So instead we have a separate driver.
