If an error occurs after calling list_add(), the &l2cache_pmu->clusters list will reference some memory that will be freed when the managed resources will be released. Move the list_add() at the end of the function when everything is in fine. This is harmless because if l2_cache_pmu_probe_cluster() fails, then l2_cache_pmu_probe() will fail as well and 'l2cache_pmu' will be released as well. But it looks cleaner and could silence static checker warning.

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.
