[ Upstream commit daa6eb5a149519583c8a8cb31945f06417d21902 ]
Upon reusing the ptp_qoriq driver, the ptp_qoriq_free() function was
used on the remove path to free any allocated resources.
The ptp_qoriq IRQ is among these resources that are freed in
ptp_qoriq_free() even though it is also a managed one (allocated using
devm_request_threaded_irq).
Drop the resource managed version of requesting the IRQ in order to not
trigger a double free of the interrupt as below:

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.
