Wen Yang ff7a5a0a85 PCI: mediatek: Fix a leaked reference by adding missing of_node_put()
The call to of_get_next_child() returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.

irq_domain_add_linear() also calls of_node_get() to increase refcount,
so irq_domain will not be affected when it is released.

Detected by coccinelle with the following warnings:
  ./drivers/pci/controller/pcie-mediatek.c:577:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 567, but without a corresponding object release within this function.
  ./drivers/pci/controller/pcie-mediatek.c:583:3-9: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 567, but without a corresponding object release within this function.
  ./drivers/pci/controller/pcie-mediatek.c:586:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 567, but without a corresponding object release within this function.

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.
