commit 9ab27eb5866ccbf57715cfdba4b03d57776092fb upstream.
By simply bailing out, the driver was violating its rule and internal
assumptions that either both or no rproc should be initialized. E.g.,
this could cause the first core to be available but not the second one,
leading to crashes on its shutdown later on while trying to dereference
that second instance.
Fixes: 61f6f68447ab ("remoteproc: k3-r5: Wait for core0 power-up before powering up core1")

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.
