Bastien Curutchet (Schneider Electric) a017b984db net: dsa: microchip: Free previously initialized ports on init failures 
[ Upstream commit 0f80e21bf6 ]

If a port interrupt setup fails after at least one port has already been
successfully initialized, the gotos miss some resource releasing:
- the already initialized PTP IRQs aren't released
- the already initialized port IRQs aren't released if the failure
occurs in ksz_pirq_setup().

Merge 'out_girq' and 'out_ptpirq' into a single 'port_release' label.
Behind this label, use the reverse loop to release all IRQ resources
for all initialized ports.
Jump in the middle of the reverse loop if an error occurs in
ksz_ptp_irq_setup() to only release the port IRQ of the current
iteration.

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.
