Whether started at probe() time or thereafter from the command line, a remote processor needs to be shut down before the final cleanup phases can happen. Otherwise the system may be left in an unpredictable state where the remote processor is expecting the remoteproc core to be providing services when in fact it no longer exist. Invariably calling rproc_shutdown() is fine since it will return immediately if the remote processor has already been switched off.

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.
