-/* radio-trust.c - Trust FM Radio card driver for Linux 2.2
- * by Eric Lammerts <eric@scintilla.utwente.nl>
- *
- * Based on radio-aztech.c. Original notes:

- * Adapted to support the Video for Linux API by
- * Russell Kroll <rkroll@exploits.org>. Based on original tuner code by:
- *
- * Quay Ly
- * Donald Song
- * Jason Lewis (jlewis@twilight.vtc.vsc.edu)
