e5e9f44c24 i2c: Drop I2C_CLIENT_INSMOD_2 to 8
These macros simply declare an enum, so drivers might as well declare
it themselves. This puts an end to the arbitrary limit of 8 chip types
per i2c driver.

c3813d6af1 i2c: Get rid of struct i2c_client_address_data
Struct i2c_client_address_data only contains one field at this point,
which makes its usefulness questionable. Get rid of it and pass simple
address lists around instead.

these, meaning that they are useless. Discard them, along with a few

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.)

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.

c7461a6652 [PATCH] hwmon: adm9240 driver update - dynamic sysfs
hwmon: adm9240 update 2/2: convert to use dynamic sysfs accessors

This patch converts adm9240 to use Yani Ioannou's dynamic sysfs callbacks,
reducing driver memory footprint from 16312 to 14104 bytes on 2.6.14-rc1,
removing the old driver macro mess.

Run tested on Intel SE440BX-2 mobo.

303760b44a [PATCH] hwmon: hwmon vs i2c, second round (07/11)
The only part left in i2c-sensor is the VRM/VRD/VID handling code.
This is in no way related to i2c, so it doesn't belong there. Move
the code to hwmon, where it belongs.

Note that not all hardware monitoring drivers do VRM/VRD/VID
operations, so less drivers depend on hwmon-vid than there were
depending on i2c-sensor.

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.

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.

1f57ff89fe [PATCH] drivers/hwmon/*: kfree() correct pointers
The adm9240 driver, in adm9240_detect(), allocates a structure.  The
error path attempts to kfree() ->client field of it (second one),
resulting in an oops (or slab corruption) if the hardware is not present.

->client field in adm1026, adm1031, smsc47b397 and smsc47m1 is the first in
${HWMON}_data structure, but fix them too.
