-/* SF16FMI radio driver for Linux radio support
+/* SF16-FMI and SF16-FMP radio driver for Linux radio support
* heavily based on rtrack driver...
* (c) 1997 M. Kirkwood
* (c) 1998 Petr Vandrovec, vandrove@vc.cvut.cz
*
* Frequency control is done digitally -- ie out(port,encodefreq(95.8));
* No volume control - only mute/unmute - you have to use line volume
- * control on SB-part of SF16FMI
+ * control on SB-part of SF16-FMI/SF16-FMP
*
* Converted to V4L2 API by Mauro Carvalho Chehab <mchehab@infradead.org>
