Cosmin Tanislav 4447bbdff9 mtd: parsers: ofpart: call of_node_put() only in ofpart_fail path 
[ Upstream commit 0c87dea1aa ]

ofpart_none can only be reached after the for_each_child_of_node() loop
finishes. for_each_child_of_node() correctly calls of_node_put() for all
device nodes it iterates over as long as we don't break or jump out of
the loop.

Calling of_node_put() inside the ofpart_none path will wrongly decrement
the ref count of the last node in the for_each_child_of_node() loop.

Move the call to of_node_put() under the ofpart_fail label to fix this.

Fixes: ebd5a74db7 ("mtd: ofpart: Check availability of reg property instead of name property")

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.
