Users have reported problems with recent Lenovo laptops that contain an IDEA5002 I2C HID device. Reports include fans turning on and running even at idle and spurious wakeups from suspend. Presumably in the Windows ecosystem there is an application that uses the HID device. Maybe that puts it into a lower power state so it doesn't cause spurious events. This device doesn't serve any functional purpose in Linux as nothing interacts with it so blacklist it from being probed. This will prevent the GPIO driver from setting up the GPIO and the spurious interrupts and wake events will not occur.

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.
