2778fb13ba hwmon: (lm63) Consider LM64 temperature offset
LM64 has 16 degrees Celsius temperature offset on all
remote sensor registers.
This was not considered When LM64 support was added to lm63.c.

10f2ed31aa hwmon: (lm63) Add basic support for LM64
The LM64 appears to be an LM63 with added GPIO lines. Add support for the
hwmon functionality - GPIO can be added at some later stage if someone
has a need for them.

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.

7817a39e65 hwmon: Fault files naming convention
We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:

in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault

Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.

We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.

0e39e01c90 hwmon: Fix unchecked return status, batch 4
hwmon: Fix unchecked return status, batch 4

Fix up some hwmon drivers so that they no longer ignore return status
from device_create_file().

Note: f71805f actually checked the status from device_create_file
already. However it did not remove the files on device destruction.
It was also an opportunity to use sysfs_create/remove_group instead
of hand-made loops. This makes the changes much more important but
I think the result is worth it.

hwmon: Add individual alarm files to 4 drivers

Add individual sysfs files for all f71805f, lm63, lm83 and lm90 alarm
and fault conditions. This is a requirement for the planned
chip-independent libsensors. Almost all other hwmon drivers will need
the same improvement.

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.

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.

normal_i2c could be renamed to normal, but I decided not to do so at the

as part of the i2c_probe/i2c_detect merge.
