In smmu_pmu_probe(), there is put_cpu() in the error path, which is wrong because we use raw_smp_processor_id() to get the cpu ID, not get_cpu(), remove it. While we are at it, kill 'out_cpuhp_err' altogether and just return err if we fail to add the hotplug instance.

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.
