+/*
+	Supported devices:
+	*Lifeview FlyCam Supra (using the Philips saa7111a chip)
+
+	Does any other model using the w9966 interface chip exist ?
+
+	Todo:
+
+	*Add a working EPP mode, since DMA ECP read isn't implemented
+	in the parport drivers. (That's why it's so sloow)
+
+	*Add support for other ccd-control chips than the saa7111
+	please send me feedback on what kind of chips you have.
+
+	*Add proper probing. I don't know what's wrong with the IEEE1284
+	parport drivers but (IEEE1284_MODE_NIBBLE|IEEE1284_DEVICE_ID)
+	and nibble read seems to be broken for some peripherals.
+
+	*Add probing for onboard SRAM, port directions etc. (if possible)
+
+	*Add support for the hardware compressed modes (maybe using v4l2)
+
+	*Fix better support for the capture window (no skewed images, v4l
+	interface to capt. window)
+
+	*Probably some bugs that I don't know of
+
+	Please support me by sending feedback!
+
+	Changes:
+
+	Alan Cox:	Removed RGB mode for kernel merge, added THIS_MODULE
+			and owner support for newer module locks

-/*
- *    QuickCam Driver For Video4Linux.
- *
- *	Video4Linux conversion work by Alan Cox.
- *	Parport compatibility by Phil Blundell.
- *	Busy loop avoidance by Mark Cooke.
- *
- *    Module parameters:
- *
- *	maxpoll=<1 - 5000>
- *
- *	  When polling the QuickCam for a response, busy-wait for a
- *	  maximum of this many loops. The default of 250 gives little
- *	  impact on interactive response.
- *
- *	  NOTE: If this parameter is set too high, the processor
- *		will busy wait until this loop times out, and then
- *		slowly poll for a further 5 seconds before failing
- *		the transaction. You have been warned.
- *
- *	yieldlines=<1 - 250>
- *
- *	  When acquiring a frame from the camera, the data gathering
- *	  loop will yield back to the scheduler after completing
- *	  this many lines. The default of 4 provides a trade-off
- *	  between increased frame acquisition time and impact on
- *	  interactive response.

-/*
-	Supported devices:
-	*Lifeview FlyCam Supra (using the Philips saa7111a chip)
-
-	Does any other model using the w9966 interface chip exist ?
-
-	Todo:
-
-	*Add a working EPP mode, since DMA ECP read isn't implemented
-	in the parport drivers. (That's why it's so sloow)
-
-	*Add support for other ccd-control chips than the saa7111
-	please send me feedback on what kind of chips you have.
-
-	*Add proper probing. I don't know what's wrong with the IEEE1284
-	parport drivers but (IEEE1284_MODE_NIBBLE|IEEE1284_DEVICE_ID)
-	and nibble read seems to be broken for some peripherals.
-
-	*Add probing for onboard SRAM, port directions etc. (if possible)
-
-	*Add support for the hardware compressed modes (maybe using v4l2)
-
-	*Fix better support for the capture window (no skewed images, v4l
-	interface to capt. window)
-
-	*Probably some bugs that I don't know of
-
-	Please support me by sending feedback!
-
-	Changes:
-
-	Alan Cox:	Removed RGB mode for kernel merge, added THIS_MODULE
-			and owner support for newer module locks
