[PATCH] hwmon: hwmon vs i2c, second round (04/11)

i2c_probe and i2c_detect now do the exact same thing and operate on
the same data structure, so we can have everyone call i2c_probe.

For `sensors' drivers, use the i2c_detect function instead:

Remember, structure `addr_data' is defined by the macros explained above,
so you do not have to define it yourself.
The i2c_probe or i2c_detect function will call the foo_detect_client
The i2c_probe function will call the foo_detect_client
function only for those i2c addresses that actually have a device on
them (unless a `force' parameter was used). In addition, addresses that
are already in use (by some other registered client) are skipped.

The detect client function
--------------------------
The detect client function is called by i2c_probe or i2c_detect.
The `kind' parameter contains 0 if this call is due to a `force'
parameter, and -1 otherwise (for i2c_detect, it contains 0 if
this call is due to the generic `force' parameter, and the chip type
number if it is due to a specific `force' parameter).
The detect client function is called by i2c_probe. The `kind' parameter
contains -1 for a probed detection, 0 for a forced detection, or a positive
number for a forced detection with a chip type forced.
Below, some things are only needed if this is a `sensors' driver. Those
parts are between /* SENSORS ONLY START */ and /* SENSORS ONLY END */
