commita371c10ea4upstream. As-per suggestion from FlexRM HW folks, we have to first set FlexRM ring flush state and then clear it for FlexRM ring flush to work properly. Currently, the FlexRM driver has incomplete FlexRM ring flush sequence which causes repeated insmod+rmmod of mailbox client drivers to fail. This patch fixes FlexRM ring flush sequence in flexrm_shutdown() as described above.

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.
