Currently all probed sensor types are emitted in the kernel log, generating unnecessary noise. Be less verbose and only report what sensor is found (if any)

Subject: V4L/DVB (13897): gspca - main: Check the interface class at probe
 time.

The USB video interface was checked as having the number zero, but
some webcams have other values. The test is now done on the interface
class which may be either 255 (vendor spec) or 0 (class per interface).

Subject: V4L/DVB (13898): gspca - some subdrivers: Make sd_desc const.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The function callbacks in sd_desc are defined at compile time and
they do not change at runtime. Make the sd_desc initializations const.

Subject: V4L/DVB (13899): gspca - all subdrivers: Make control descriptors
 constant.

The ctrls field of struct sd_desc is declared as const
in gspca.h. It is worth to initialize the content also with
constant values.

Subject: V4L/DVB (13925): gspca - main: Change the check of the USB video
 interface.

Some webcams have many interfaces with the same interface class, so the
previous interface check did not work.
The new code checks if the interface number is zero or the only one.

Subject: V4L/DVB (13926): gspca - pac7302: Fix a random USB error.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When loading the register 0x49 of the page 3, the usb_control_msg() sometimes
fails with error -71 or -62.
This change skips loading the register 0x48.

Subject: V4L/DVB (13952): gspca: Storage class should be before const
 qualifier

The C99 specification states in section 6.11.5:

The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.

Subject: V4L/DVB (13991): gspca_mr973010a: Fix cif type 1 cameras not
 streaming on UHCI controllers

If you read the mail to Oliver Neukum on the linux-usb list, then you know
that I found a cure for the mysterious problem that the MR97310a CIF "type
1" cameras have been freezing up and refusing to stream if hooked up to a
machine with a UHCI controller.

Namely, the cure is that if the camera is an mr97310a CIF type 1 camera, you
have to send it 0xa0, 0x00. Somehow, this is a timing reset command, or
such. It un-blocks whatever was previously stopping the CIF type 1 cameras
from working on the UHCI-based machines.

Subject: V4L/DVB (13995): gspca_ov519: mark led on eyetoy II as inverted

Mark led on eyetoy II as inverted, I have the feeling the led needs to
be inverted for all 519 based cams (iow we got the set led code wrong), but
lets just deal with this one cam at a time to avoid breaking currently
working cams.

Subject: V4L/DVB (13997): gspca_ov519: differentiate ov7620 and ov7620ae and
 fix 640x480 on the 7620

Michael Deegan <michael@ucc.gu.uwa.edu.au>, has reported issues with
using 640x480 mode on his ov518+ webcam. The fix for this breaks things
on my ov518+ cam (Trust 320 Sp@cecam), this patch thus adds differentiation
in the driver between the OV7620 sensor his cam has and the OV7620AE sensor
my cam has, and then only changes the init sequence for the ov518+ +
OV7620 combo which was not working for Michael.

Our hstart value was wrong for tas5110d sensor using sonixb cams, this
patch fixes this. Many thanks to Paulus (laudaka) for donating me a camera
with such a sensor IC.

From: Hans de Goede <hdegoede@redhat.com>
Date: Thu, 14 Jan 2010 09:37:18 -0300
Subject: V4L/DVB (14003): gspca_cpai1: New gspca subdriver for CPIA CPiA
 version 1 cams

This new driver supports USB PIA CPiA version 1 cams, replacing the
old v4l1 driver.

Subject: V4L/DVB: gspca - zc3xx: Change the resolutions of some sensors

The sensors adcm2700, mc501cb and ov7620 cannot have the full height
permitted by the zc3xx bridges. This change removes 8 pixels at the
bottom of the images.

Subject: V4L/DVB: gspca - ov534: Fix end of frame handling

Fix a regression, introduced in the driver split, which made
the ov534 driver unusable.
Plus, the debug message should reflect that we discard also packets
beyond the expected frame size.

From 26984b09952d01afabaa38e747fbee083dde0374 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Mon, 1 Feb 2010 13:18:37 -0300
Subject: V4L/DVB: gscpa_sonixb: Differentiate between sensors with a coarse
 and fine expo ctrl

Some sensors only allow controlling the exposure by changing the clockdiv,
which means that exposure takes pretty large jumps (for example when going
from a div of 1 to 2, the exposure doubles). Use 2 different entries in
the controls array for these 2 different types of exposure (always
disabling one), and;

Add a new autogain algorithm for the coarse exposure case, which normally
changes the gain setting, only touching the exposure setting if the desired
luminance cannot be reached with gain, and after an exposure change once more
first tries gain, etc. Thus avoiding exposure changes, and the resulting
oscilation because of the huge steps these exposure controls take.

+/* Autogain + exposure algorithm for cameras with a coarse exposure control
+   (usually this means we can only control the clockdiv to change exposure)
+   As changing the clockdiv so that the fps drops from 30 to 15 fps for
+   example, will lead to a huge exposure change (it effectively doubles),
+   this algorithm normally tries to only adjust the gain (between 40 and
+   80 %) and if that does not help, only then changes exposure. This leads
+   to a much more stable image then using the knee algorithm which at
+   certain points of the knee graph will only try to adjust exposure,
+   which leads to oscilating as one exposure step is huge.
+
+   Note this assumes that the sd struct for the cam in question has
+   exp_too_high_cnt and exp_too_high_cnt int members for use by this function.
+
+   Returns 0 if no changes were made, 1 if the gain and or exposure settings
+   where changed. */

Subject: V4L/DVB: gspca_sonixb: pas202: fixup brightness ctrl and add gain and
 exposure ctrls

Fixup brightness ctrl and add gain and exposure ctrls for PAS202BCB sensors,
this allows enabling autogain (done), and makes the cam usable in low light
conditions.

Subject: V4L/DVB: gspca_sonixb: pas106: fixup bright ctrl and add gain and
 exposure ctrls

Fixup brightness ctrl and add gain and exposure ctrls for PAS106B sensors,
this allows enabling autogain (done), and makes the cam usable in low light
conditions.

Subject: V4L/DVB: gspca_pac7302: much improved exposure control

My experience with fixing up the controls for the PAS sensors in
sonixb, has lead me to re-investigate the exposure control for the
pac7302. I've now found a regular exposure register in register bank 3
(which seems to be the sensor registers bank), and with this added a proper
fine grained exposure control. This patch also updates the do_autogain
function to work properly with this new finer grained control.

Subject: V4L/DVB: gspca_main: some input error handling fixes

2 small changes to input device error handling:
1) Make it fatal when we fail to create an input device (it is either this
   or add checks for gspca_dev->input_dev being NULL in a lot of places)
2) Since we allow gspca_input_create_urb() to fail everywhere we call it,
   and thus never check its return value, make it void.
