If the chip isn't recognized, then the correct errors should be returned.
The v4l2_i2c_attach() utility function will return 0 for all errors
except -ENOMEM to provide proper compatibility support for the old I2C
probing function.

The chip matching in struct v4l2_register was rather primitive. It could
not be extended to other busses besides i2c and it lacked a way to
differentiate between two i2c chips driven by the same driver on one
board (e.g. a PVR500 with two tuner chips, one for analog TV and one for
radio).
It has now been improved making it much more powerful.

Add -include linux/version.h to the cflags. Now code can have backward
compatibility test without including compat.h first.
Linux headers included from compat.h are removed, so that code will get
the same headers when compiling in v4l-dvb as it does in the kernel.
Many drivers have compat.h moved to the end of their include list, as
this lets compat.h do things it can't do at the beginning. Such as test
of something is defined to include compat code, or to put a wrapper
around a function without changing the function's name.

Before, root privileges were only needed to set hardware registers, not
to read them. On some hardware, reading from the wrong place at the
wrong time can hang the machine. So, to be consistent, root privileges
are required to read registers on all hardware.

The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such. Officially export them.
VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h
to videodev2.h.
Types used in struct v4l2_register are changed to the userspace
exportable versions (u32 -> __u32, etc).
Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move
the check into the video_ioctl2() dispatcher so it doesn't need to be
duplicated in each driver's call-back function.
CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2).
