These are the last remaining device drivers using
the ->ioctl file operation in the drivers directory
(except from v4l drivers).

Recent changes on the I2C front have left off-by-one array indexes in
3 hwmon drivers. Fix them.

When /dev/watchdog gets opened a second time we return -EBUSY, but
we already have got a kref then, so we end up leaking our data struct.

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.

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.

The "kind" parameter always has value -1, and nobody is using it any
longer, so we can remove it.

As kind is now hard-coded to -1, there is room for code clean-ups.

At the moment, dmi_walk() lacks flexibility, users can't pass data to
the callback function. Add a pointer for private data to make this
function more flexible.
