+ * Guillemot Maxi Radio FM 2000 PCI radio card driver for Linux
* (C) 2001 Dimitromanolakis Apostolos <apdim@grecian.net>
*
* Based in the radio Maestro PCI driver. Actually it uses the same chip
* for radio but different pci controller.
*
* I didn't have any specs I reversed engineered the protocol from
- * the windows driver (radio.dll).
+ * the windows driver (radio.dll).
*
* The card uses the TEA5757 chip that includes a search function but it
- * is useless as I haven't found any way to read back the frequency. If
+ * is useless as I haven't found any way to read back the frequency. If
* anybody does please mail me.
*
* For the pdf file see:
* - tiding up
* - removed support for multiple devices as it didn't work anyway
*
- * BUGS:
+ * BUGS:
* - card unmutes if you change frequency
