In a pipelined engine situation, we might either have the host which internally has support for error correction, or have it using an external hardware block for this purpose. In the former case, the host is also the ECC engine. In the latter case, it is not. In order to get the right pointers on the right devices (for example: in order to devm_* allocate variables), let's introduce this helper which can safely be called by pipelined ECC engines in order to retrieve the right device structure.

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.
