[ Upstream commit 9995dbfc2235efabdb3759606d522e1a7ec3bdcb ]
Commit f3f11cfe8907 ("remoteproc: k3-r5: Acquire mailbox handle during
probe routine") introduced a check in the "k3_r5_rproc_mbox_callback()"
and "k3_r5_rproc_kick()" callbacks, causing them to exit if the remote
core's state is "RPROC_DETACHED". However, the "__rproc_attach()"
function that is responsible for attaching to a remote core, updates
the state of the remote core to "RPROC_ATTACHED" only after invoking
"rproc_start_subdevices()".
The "rproc_start_subdevices()" function triggers the probe of the Virtio
RPMsg devices associated with the remote core, which require that the
"k3_r5_rproc_kick()" and "k3_r5_rproc_mbox_callback()" callbacks are
functional. Hence, drop the check in the callbacks.

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.
