+ * tw68_controls.c
+ * Part of the device driver for Techwell 68xx based cards
+ *
+ * Much of this code is derived from the cx88 and sa7134 drivers, which
+ * were in turn derived from the bt87x driver. The original work was by
+ * Gerd Knorr; more recently the code was enhanced by Mauro Carvalho Chehab,
+ * Hans Verkuil, Andy Walls and many others. Their work is gratefully
+ * acknowledged. Full credit goes to them - any problems within this code
+ * are mine.
