Managed resources in the driver should be automatically cleaned up on driver detach. It's unnecessary to manually free/unmmap these resources. One of the manual cleanup causes static checkers to complain. The bug is reported by Dan Carpenter <dan.carpenter@oracle.com> in [1] [1] https://www.spinics.net/lists/arm-kernel/msg593012.html This patch gets rid of all the unnecessary manual cleanup and properly unregister all the registered PMU devices by the driver on driver detach.

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.
