*
* 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 SF16-FMI/SF16-FMP
+ * control on SB-part of SF16-FMI/SF16-FMP/SF16-FMD
*
* Converted to V4L2 API by Mauro Carvalho Chehab <mchehab@infradead.org>
