1975d16786 hwmon: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

subsystem. Conversion is 1:1 because the return value is not used.

ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

952a11ca32 hwmon: cleanup non-bool "valid" data fields
We have bool so use it consistently in all the drivers.

The following Coccinelle script was used:

@@
identifier T;
type t = { char, int };
@@
struct T {
...
-	t valid;
+	bool valid;
...
}

@@
identifier v;
@@
(
- v->valid = 0
+ v->valid = false
|
- v->valid = 1
+ v->valid = true
)

followed by sed to fixup the comments:
sed '/bool valid;/{s/!=0/true/;s/zero/false/}'

Few whitespace changes were fixed manually. All modified drivers were
compile-tested.

fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.
