/* zoltrix radio plus driver for Linux radio support
* (c) 1998 C. van Schaik <carl@leg.uct.ac.za>
*
- * BUGS
+ * BUGS
* Due to the inconsistency in reading from the signal flags
* it is difficult to get an accurate tuned signal.
*
*
* 1999-05-06 - (C. van Schaik)
* - Make signal strength and stereo scans
- * kinder to cpu while in delay
+ * kinder to cpu while in delay
* 1999-01-05 - (C. van Schaik)
* - Changed tuning to 1/160Mhz accuracy
* - Added stereo support
* - Added unmute function
* - Reworked ioctl functions
* 2002-07-15 - Fix Stereo typo
+ *
+ * 2006-07-24 - Converted to V4L2 API
