e4b880758a HID: i2c-hid: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("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.

4122abfed2 HID: i2c-hid: acpi: Unify ACPI ID tables format
Unify ACPI ID tables format by:
- surrounding HID by spaces
- dropping unnecessary driver_data assignment to 0
- dropping comma at the terminator entry

572eaeb7fa HID: i2c-hid: acpi: Drop unneded NULL check of adev
The driver is enumerated on ACPI platforms, so adev is valid.
Since there is no valid I²C ID table provided, there is no
possibility to bind a device to this driver via user space.
Hence, drop unneeded NULL check of adev.

0960941043 HID: i2c-hid: acpi: Drop redundant ACPI_PTR()
The driver depends on ACPI, ACPI_PTR() resolution is always the same.
Otherwise a compiler may produce a warning.

That said, the rule of thumb either ugly ifdeffery with ACPI_PTR or
none should be used in a driver.

6d97010eb9 HID: i2c-hid: acpi: Get ACPI companion only once and reuse it

b33752c300 HID: i2c-hid: Reorganize so ACPI and OF are separate modules
This patch rejiggers the i2c-hid code so that the OF (Open Firmware
aka Device Tree) and ACPI support is separated out a bit.  The OF and
ACPI drivers are now separate modules that wrap the core module.

Essentially, what we're doing here:
* Make "power up" and "power down" a function that can be (optionally)
  implemented by a given user of the i2c-hid core.
* The OF and ACPI modules are drivers on their own, so they implement
  probe / remove / suspend / resume / shutdown.  The core code
  provides implementations that OF and ACPI can call into.

We'll organize this so that we now have 3 modules: the old i2c-hid
module becomes the "core" module and two new modules will depend on
it, handling probing the specific device.

As part of this work, we'll remove the i2c-hid "platform data"
concept since it's not needed.
