- * Media Vision Pro Movie Studio
- * or
- * "all you need is an I2C bus some RAM and a prayer"
- *
- * This draws heavily on code
- *
- * (c) Wolfgang Koehler, wolf@first.gmd.de, Dec. 1994
- * Kiefernring 15
- * 14478 Potsdam, Germany
- *
- * Most of this code is directly derived from his userspace driver.
- * His driver works so send any reports to alan@lxorguk.ukuu.org.uk
- * unless the userspace driver also doesn't work for you...
- *
- * Changes:
- * 25-11-2009 Hans Verkuil <hverkuil@xs4all.nl>
- * - converted to version 2 of the V4L API.
- * 08/07/2003 Daniele Bellucci <bellucda@tiscali.it>
