[ Upstream commit e3cb82c6d6f6c27ab754e13ae29bdd6b949982e2 ] When commit c64ffff7a9d1 ("i2c: core: Allow empty id_table in ACPI case as well") fixed the enumeration of I²C devices on ACPI enabled platforms when driver has no ID table, it missed the PRP0001 support. i2c_device_match() and i2c_acpi_match_device() differently match driver against given device. Use acpi_driver_match_device(), that is used in the former, in i2c_device_probe() and don't fail PRP0001 enumeration when no ID table exist.

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.
