V4L/DVB (4364): V4L2 conversion: radio-maxiradio
Driver conversion to V4L2 API.
Require some testing, since this obsolete hardware is not
common those days.

+ * 0.75 Sun Feb 4 22:51:27 EET 2001
* - tiding up
* - removed support for multiple devices as it didn't work anyway
*
* BUGS:
* - card unmutes if you change frequency
