In the PRP0001 case, the compatible string may have additional data affiliated with the device. When we call device_get_match_data() on such device, we will get nothing since currently acpi_device_get_match_data() doesn't respect PRP0001. To fix the above, try acpi_of_match_device() if there is no ACPI table in the driver. Anyway, note that the device is expected to get its own proper ACPI ID.

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.
