b39423a95c V4L/DVB (5580): Add support for three cards to saa7134 driver
Add support for the "Elitegroup ECS TVP3XP FM1246", the "KWorld DVB-T
210", and the Animation Technologies LR214 Rev F onwards (SAA7131) to
the saa7134 driver.
Also rename the LR214WF to the LR214 Rev E or ealier (SAA7135), to match
what we've seen on boards in the field.
Changed the comment on the Lifeview cards to indicate Rev E and earlier
versus Rev F and later, together with a chip indicator, following
feedback from Peter Missel <peter.missel@onlinehome.de>.

This causes the cx25840 module to treat V4L2_STD_PAL_60 similar to

5c808e6417 V4L/DVB (5575): Pvrusb2: Implement ability to disable IR receiver
Anyone using multiple PVR USB2 devices really only want one of them
acting as the actual IR receiver.  

Implemented here is a new per-instance module option (ir_mode) which is 
a flag to enable the IR receiver.  The default is enabled.  

IR reception is disabled by blocking access to the IR receiver chip in 
the device.

as a module option).

4f393828d1 V4L/DVB (5573): Pvrusb2: kill unnecessary attribute->owner
sysfs is now completely out of driver/module lifetime game.

After deletion, a sysfs node doesn't access anything outside sysfs 
proper, so there's no reason to hold onto the attribute owners.

Note that often the wrong modules were accounted for as owners leading 
to accessing removed modules. 

This patch kills now unnecessary attribute->owner.  

Note that with this change, userland holding a sysfs node does not 
prevent the backing module from being unloaded. 

For more info regarding lifetime rule cleanup, please read the following

6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

arch/alpha/kernel/err_common.c
arch/alpha/kernel/err_ev6.c
arch/alpha/kernel/err_ev7.c

sound/oss/au1550_ac97.c

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:

The code was testing an 8-bit address against a 7-bit address.  Will the
confusion of the two never cease?
Biggest flaw of the I2C protocol:  the R/W bit is the LSB instead of the
MSB.  No one can ever agree if addresses are 7-bits and the R/W bit
follows them, or if they are 8-bit and the R/W bit is OR-ed into the
address byte.  If the R/W bit was first, it wouldn't make any difference!

- change a printk to PDEBUG when USB probe detects an unknown device.
This will avoid a message log from usbvision when an unclaimed device is inserted.

c682b3a7fb V4L/DVB (5517): Usbvision: store the device database more efficiently
One bit wide bitfields need to declared unsigned to have the range 0 to
1, or they have the range -1 to 0.

A few techniques to reduce the driver's size by about 1700 bytes on ia32,
probably more on x86-64.

Put the biggest fields first, less padding is necessary that way.

Put fields with a limited range into a smaller type.  For example
VideoChannels will fit in 3 bits, and TunerType can use 8 bits.

Vin_Reg1, Vin_Reg2, and Dvi_yuv define values for 8-bit registers, but
they can't just go into an 8-bit field with no changes, since -1 was used
as a flag to indicate a value was not present.  So what we do is create a
one-bit flag for each one to indicate if a value is or is not present.

This only takes 9 bits and has the added advantage that when the register
isn't overridden (Vin_Reg[12] never are) it doesn't need to appear in the
structure definition since the default value for the flag will be zero.

659ae56dcd V4L/DVB (5515): Use a better format to represent usbvision supported boards
Changed usbvision cards table to allow:
	1) Not repeat USB ID on two structs;
	2) Not need to specify both usb and card description tables at
	   the same order, removing some magic;
Some cards had duplicated names. Fixed.
A test for an specific board were doing by using a string comparation.
The comparation were wrong. Also, it is not a good practice to recognize
a board based on his string name.

31a1854706 V4L/DVB (5507): Pvrusb2: Gather USB bus address info and report it
The V4L2 API requires a unique bus_info string returned as part of the
v4l2_capability structure.  These changes gather up the USB address
information, from the underlying device, into a string and report that
out through v4l2 and via sysfs (for completeness).

c680dd6038 V4L/DVB (5502): Sn9c102: more efficient register writing code
There were many places in the driver which had long sequences of constant
register initializations.  These were done with one function call per
register.  The register address and value were immediate values in the
function calls.
This is very inefficient, as each register and value take twice the space
when they are code, as each includes a push instruction to put it on
the stack.  There there is the overhead, both size and time, for a
function call for each register.  It's also quite a few lines of C code
to do this.
The patch creates a function that writes multiple registers from a list,
and a macro that makes it easy to construct a such a list as a const
static local to send to the function.
This gets rid of quite a bit of C code, and shrinks the driver by around
8k, while at the same time being more efficient.
