commitfb03082a54upstream. In the commit4f0a1a1ae3("memory: mtk-smi: Invoke pm runtime_callback to enable clocks"), we use pm_runtime callback to enable/disable the smi larb clocks. It will cause the larb's clock may not be disabled when suspend. That is because device_prepare will call pm_runtime_get_noresume which will keep the larb's PM runtime status still is active when suspend, then it won't enter our pm_runtime suspend callback to disable the corresponding clocks. This patch adds suspend pm_ops to force disable the clocks, Use "LATE" to make sure it disable the larb's clocks after the multimedia devices.

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.
