+/* saa7115 - Philips SAA7114/SAA7115 video decoder driver
+ *
+ * Based on saa7114 driver by Maxim Yevtyushkin, which is based on

+ *
+ * Copyright (C) 1998 Dave Perks <dperks@ibm.net>

+ *
+ * Moved over to the linux >= 2.4.x i2c protocol (1/1/2003)
+ * by Ronald Bultje <rbultje@ronald.bitfreak.net>
+ *
+ * Added saa7115 support by Kevin Thayer <nufan_wfk at yahoo.com>
