Commitac75a04104("HID: i2c-hid: fix size check and type usage") started writing messages when the ret_size is <= 2 from i2c_master_recv. However, my device i2c-DLL07D1 returns 2 for a short period of time (~0.5s) after I stop moving the pointing stick or touchpad. It varies, but you get ~50 messages each time which spams the log hard. [ 95.925055] i2c_hid i2c-DLL07D1:01: i2c_hid_get_input: incomplete report (83/2) This has also been observed with a i2c-ALP0017. [ 1781.266353] i2c_hid i2c-ALP0017:00: i2c_hid_get_input: incomplete report (30/2) Only print the message when ret_size is totally invalid and less than 2 to cut down on the log spam.

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.
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.
