Harini T 4e5a929f5c mailbox: zynqmp-ipi: Remove dev.parent check in zynqmp_ipi_free_mboxes
[ Upstream commit 019e3f4550fc7d319a7fd03eff487255f8e8aecd ]

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().

README

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.
