The init code path has several exceptions where the driver can decide not to load. As CONFIG_X86_INTEL_PSTATE is generally set to Y, the return code is not reachable. The initialization code is neither verbose of the reason why it did choose to prematurely exit, so it is difficult for a user to determine, on a given platform, why the driver didn't load properly. This patch is about reporting to the user the reason/context of why the driver failed to load. That is a precious hint when debugging a platform.

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.
