i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()
Hans de Goede authored 
[ Upstream commit 21653a41 ]

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.

============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
