intel_rapl driver used to have a list of cpuids, which is used to 1. check if the processor support RAPL MSRs 2. do some cpu model specific setting 3. module autoloading Now, the cpu model specific setting are moved to intel_rapl_common.c as part of the common code, because the setup is also needed by RAPL MMIO interface on those platforms. But removing the cpuid list from intel_rapl MSR interface driver results in that the driver can not be loaded automatically. Maintaining another copy of the cpuid list in intel_rapl_msr.c does not make sense because it increases the complexity when enabling RAPL support on a new cpu model. Fix the problem by creating an "intel_rapl_msr" platform device in the common code, and make RAPL MSR interface driver (intel_rapl_msr.c) probe the platform device directly.

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.
