833bedb813 i2c: Convert the pcf8574 driver to a new-style i2c driver
The new-style pcf8574 driver implements the optional detect() callback
to cover the use cases of the legacy driver.

Warning: users will now have to use the force module parameter to get
the driver to attach to their device. That's not a bad thing as these
devices can't be detected anyway.

Note that this doesn't change the fact that this driver is deprecated
in favor of gpio/pcf857x.

f741f67329 i2c: Clean up old chip drivers
Clean up old i2c chip drivers:
* Name the i2c_client "client" instead of "new_client".
* Drop useless initializations to 0.

7b501b1f53 hwmon: Discard useless I2C driver IDs
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.

553515e5c5 i2c/pcf8574: No arbitrary initialization
Do not initialize the PCF8574 with an arbitrary value. Users will have
to write the initial value to sysfs themselves.

7d9db67feb i2c: __must_check fixes (chip drivers)
i2c: __must_check fixes (chip drivers)

Check for error on sysfs file creation.
Delete sysfs files on device removal.

The approach taken for the most complex case (pcf8591) is similar to
what Mark M. Hoffman proposed for hardware monitoring chip drivers.

2b48716d1d [PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer needed
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.)

a9718b0c11 [PATCH] i2c: Drop i2c_driver.{owner,name}, 2 of 11
We should use the i2c_driver.driver's .name and .owner fields
instead of the i2c_driver's ones.

This patch updates the miscellaneaous i2c chip drivers.

8a9947552d [PATCH] i2c: Drop i2c_driver.flags, 2 of 3
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.

f4b5026120 [PATCH] hwmon: hwmon vs i2c, second round (06/11)
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.

7bef559455 [PATCH] I2C: refactor message in i2c_detach_client
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.

5071860aba [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (7/9)
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.

eb071cbbc3 [PATCH] I2C: pcf8574 driver cleanup
I found a possible cleanup in the pcf8574 driver. We don't need to store
the read value in our private data structure, as we then never use it
again. I asked Aurelien and he is fine with the change. Please apply,
thanks.

Linus Torvalds
1da177e4c3 Linux-2.6.12-rc2
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!
