[ Upstream commitd94a69cb2c] The issue takes place in one error path of clusterip_tg_check(). When memcmp() returns nonzero, the function simply returns the error code, forgetting to decrease the reference count of a clusterip_config object, which is bumped earlier by clusterip_config_find_get(). This may incur reference count leak. Fix this issue by decrementing the refcount of the object in specific error path.

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.
