[ Upstream commit019e3f4550] The ipi_mbox->dev.parent check is unreliable proxy for registration status as it fails to protect against probe failures that occur after the parent is assigned but before device_register() completes. device_is_registered() is the canonical and robust method to verify the registration status. Remove ipi_mbox->dev.parent check in zynqmp_ipi_free_mboxes().

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.
