commit4ec93f070eupstream. i2sbus_add_dev() keeps the matched "sound" child pointer after for_each_child_of_node() has dropped the iterator reference. Take an extra reference before saving that node and drop it after the layout-id/device-id lookup is complete. The function also stores np in dev->sound.ofdev.dev.of_node without taking a reference for the embedded soundbus device. Since i2sbus overrides the embedded platform device release callback, balance that reference explicitly in the local error path and in i2sbus_release_dev().

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.
