-/* Maestro PCI sound card radio driver for Linux support
- * (c) 2000 A. Tlalka, atlka@pg.gda.pl
- * Notes on the hardware
- *
- *  + Frequency control is done digitally 
- *  + No volume control - only mute/unmute - you have to use Aux line volume
- *  control on Maestro card to set the volume
- *  + Radio status (tuned/not_tuned and stereo/mono) is valid some time after
- *  frequency setting (>100ms) and only when the radio is unmuted.
- *  version 0.02
- *  + io port is automatically detected - only the first radio is used
- *  version 0.03
- *  + thread access locking additions
- *  version 0.04
- * + code improvements
- * + VIDEO_TUNER_LOW is permanent
