- This driver is DEPRECATED please use the gspca ov519 module
- instead. Note that for the ov511 / ov518 support of the gspca module
- you need atleast version 0.6.0 of libv4l and for the w9968cf
- atleast version 0.6.3 of libv4l.

- Support for the OmniVision OV6xxx and OV7xxx series of camera chips.
- This driver is intended to be used with the ov511 and w9968cf USB
- camera drivers.
-
- To compile this driver as a module, choose M here: the
- module will be called ovcamchip.

- * STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
- *
- * Thanks to STMicroelectronics for information on the usb commands, and
- * to Steve Miller at STM for his help and encouragement while I was
- * writing this driver.
- *
- * This driver is based heavily on the
- * Endpoints (formerly known as AOX) se401 USB Camera Driver
- * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
- *
- * Still somewhat based on the Linux ov511 driver.
- *

- * under the terms of the GNU General Public License as published by the
- * Free Software Foundation; either version 2 of the License, or (at your
- * option) any later version.
- *
- * This program is distributed in the hope that it will be useful, but
- * WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY

- *
- * You should have received a copy of the GNU General Public License
- * along with this program; if not, write to the Free Software Foundation,
- * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * History:
- * ver 0.1 October, 2001. Initial attempt.
- *
- * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
- * function, made more stable (?)
- *
- * ver 0.21 Nov, 2001. Added gamma correction and white balance,
- * due to Alexander Schwartz. Still trying to
- * improve stablility. Moved stuff into stv680.h
- *
- * ver 0.22 Nov, 2001. Added sharpen function (by Michael Sweet,
- * mike@easysw.com) from GIMP, also used in pencam.
- * Simple, fast, good integer math routine.
- *
- * ver 0.23 Dec, 2001 (gkh)
- * Took out sharpen function, ran code through
- * Lindent, and did other minor tweaks to get
- * things to work properly with 2.5.1
- *
- * ver 0.24 Jan, 2002 (kjs)
- * Fixed the problem with webcam crashing after
- * two pictures. Changed the way pic is halved to
- * improve quality. Got rid of green line around
- * frame. Fix brightness reset when changing size
- * bug. Adjusted gamma filters slightly.
- *
- * ver 0.25 Jan, 2002 (kjs)
- * Fixed a bug in which the driver sometimes attempted
- * to set to a non-supported size. This allowed
- * gnomemeeting to work.
- * Fixed proc entry removal bug.

Subject: [PATCH 6/6] Remove obsolete zc0301 v4l driver
Duplicate functionality with the gspca_zc3xx driver, zc0301 only
supports 2 USB-ID's (because it only supports a limited set of
sensors) wich are also supported by the gspca_zc3xx driver
(which supports 53 USB-ID's in total).

You forgot to remove the conditionnal compilation in the gspca_zc3xx
driver (USB_DEVICE(0x046d, 0x08ae) in gspca/zc3xx.c)

Right, thanks for pointing this out!
Attached is the updated patch, please use this one instead.
Thanks!

From: Amerigo Wang <amwang@redhat.com>
Subject: [PATCH v2 6/6] Remove obsolete zc0301 v4l driver
Duplicate functionality with the gspca_zc3xx driver, zc0301 only
supports 2 USB-ID's (because it only supports a limited set of
sensors) wich are also supported by the gspca_zc3xx driver
(which supports 53 USB-ID's in total).
