vfree() does it's own NULL checking,so no need for check before

It is no longer needed to use a struct pointer as argument, since v4l2_subdev
doesn't require that ioctl-like approach anymore. Instead just pass the input,
output and config (new!) arguments directly.

Add missing URB_NO_TRANSFER_DMA_MAP flag, since the use of consistent memory

Patch removes err() macros from few usb devices.
It places pr_err in pvrusb2-v4l2.c, dev_err in dabusb and in usbvision
drivers. Beside placing dev_err, patch defines new s2255_dev_err macro
with S2255_DRIVER_NAME in s2255 module.

remove CONFIG_KMOD from drivers
Straight forward conversions to CONFIG_MODULE; many drivers
include <linux/kmod.h> conditionally and then don't have any
other conditional code so remove it from those.

Due to several internal API changes on kernel, kernel backward
compatibility were lost. Basically, compat.h should be the last include
for it to work properly.
This patch basically reorders kernel headers to allow backward compat to
work fine.
Also:
Some includes were added after some non-include macros, on old drivers.
Better to keep all includes at the beginning of the files.

The ioctl entry point, a big switch/case, is splitted in little functions.
These functions are set as callbacks for the video_ioctl2 video4linux facility.
This improves the driver memory consumption and enables the v4l1 compatibility as a side effect.

From: Trent Piepho <xyzzy@speakeasy.org>
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.
