mbox_request_channel() returning value was changed in case of error.
It uses returning value of of_parse_phandle_with_args().
It is returning with -ENOENT instead of -ENODEV when no mboxes property
exists.
Fixes: 24fdd5074b20 ("mailbox: use error ret code of of_parse_phandle_with_args()")

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 reStructuredText 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.
