4a9e6a9230 hwmon: Use named initializers for arrays of i2c_device_data 
While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.

The mentioned robustness is relevant for a planned change to struct
i2c_device_id that replaces .driver_data by an anonymous union.

While touching all these arrays, unify indention and usage of commas.

This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64
builds.

cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

    awk -i inplace '

10a0575ea0 hwmon: (nct6775-i2c) Use i2c_get_match_data() 
Use preferred i2c_get_match_data() instead of of_match_device() and
i2c_match_id() to get the driver match data. With this, adjust the
includes to explicitly include the correct headers.

Adjust the 'kinds' enum to not use 0, so that no match data can be
distinguished from a valid enum value.

aee395bb19 hwmon: (nct6755) Add support for NCT6799D 
NCT6799D is mostly compatible to NCT6798D, with minor variations.

Note that NCT6798D and NCT6799D have a new means to select temperature
sources, and to report temperatures from those sources. This is not
currently implemented, meaning that most likely not all temperatures
are reported.

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.

6bb77c55b0 hwmon: (nct6775) Add i2c driver 
This driver provides an i2c I/O mechanism for the core nct6775 driver,
as might be used by a BMC.  Because the Super I/O chip is shared with
the host CPU in such a scenario (and the host should ultimately be in
control of it), the i2c driver is strictly read-only to avoid
interfering with any usage by the host (aside from the bank-select
register, which seems to be replicated for the i2c interface).
