The EE1004 SPD data structure advertises the presence of a thermal sensor on a DDR4 module in byte 14, bit 7. Let's use this information to explicitly instantiate the thermal sensor I2C client instead of having to rely on class-based I2C probing. The temp sensor i2c address can be derived from the SPD i2c address, so we can directly instantiate the device and don't have to probe for it. If the temp sensor has been instantiated already by other means (e.g. class-based auto-detection), then the busy-check in i2c_new_client_device will detect this. Patch was successfully tested with a Corsair Vengeance RGB PRO DDR4 module which comes with a thermal sensor.

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.
