[ Upstream commit 51c99dd2c06b234575661fa1e0a1dea6c3ef566f ] We can not call dev_pm_opp_of_cpumask_remove_table() freely anymore since the latest OPP core updates as that uses reference counting to free resources. There are cases where no static OPPs are added (using DT) for a platform and trying to remove the OPP table may end up decrementing refcount which is already zero and hence generating warnings. Lets track if we were able to add static OPPs or not and then only remove the table based on that. Some reshuffling of code is also done to do that.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
