Many I2C hwmon drivers define a driver ID but no other code references
these, meaning that they are useless. Discard them, along with a few
IDs which are defined but never used at all.

Here is a small fscher bugfix for 2.6.23 merging, lifted from my other fscher
work, as requested by Jean. The current driver has a control sysfs attribute,
which shows the contents of the control register, but the underlying
global_control value in the data structure currently never gets filled with
the actual contents of this register.

Here is another small fscher bugfix for 2.6.23 merging, this was caught by Jean
while reviewing my other bugfix. The driver was updating its copy of the
control register as if it was clear to write, but its regular read/write.  This
patch fixes this.

the conversion was generated via scripts, and the result was validated
automatically via a script as well.

Now that i2c_add_driver() doesn't need the module owner to be set by
hand, we can delete it from the drivers.  This patch catches all of the
drivers that I found in the current tree (if a driver sets the .owner by
hand, it's not a problem, just not needed.)

We should use the i2c_driver.driver's .name and .owner fields
instead of the i2c_driver's ones.

Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more
robust as it prevents accidental NULL pointer dereferences.

The only thing left in i2c-sensor.h are module parameter definition
macros. It's only an extension of what i2c.h offers, and this extension
is not sensors-specific. As a matter of fact, a few non-sensors drivers
use them. So we better merge them in i2c.h, and get rid of i2c-sensor.h
altogether.

We could refactor the error message 34 different i2c drivers print if
i2c_detach_client() fails in this function itself. Saves quite a few
lines of code. Documentation is updated to reflect that change.

Note that this patch should be applied after Rudolf Marek's w83792d
patches.

Kill normal_isa in header files, documentation and all chip drivers, as
it is no more used.

normal_i2c could be renamed to normal, but I decided not to do so at the
moment, so as to limit the number of changes. This might be done later
as part of the i2c_probe/i2c_detect merge.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
