I2C drivers were required to have an I2C device ID table even if were for devices that would only be registered using a specific firmware interface (e.g: OF or ACPI). But commitda10c06a04("i2c: Make I2C ID tables non-mandatory for DT'ed devices") changed the I2C core to relax the requirement and allow drivers to avoid defining this table. Unfortunately it only took into account drivers for OF-only devices and forgot about ACPI-only ones, and this was fixed by commitc64ffff7a9("i2c: core: Allow empty id_table in ACPI case as well"). But the latter didn't update the original comment, so it doesn't reflect what the code does now.

Linux kernel ============ 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.
