Hans de Goede a53d9b3ae9 i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()
[ Upstream commit 21653a4181 ]

Some ACPI i2c-devices _STA method (which is used to detect if the device
is present) use autodetection code which probes which device is present
over i2c. This requires the I2C ACPI OpRegion handler to be registered
before we enumerate i2c-clients under the i2c-adapter.

This fixes the i2c touchpad on the Lenovo ThinkBook 14-IIL and
ThinkBook 15 IIL not getting an i2c-client instantiated and thus not
working.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
