When running in software cyclic mode the driver currently does not go back to the first segment once the last segment has been reached. Effectively making the transfer non-cyclic. Fix this by going back to the first segment once the last segment has been reached for cyclic transfers. Special care need to be taken to avoid a segment from being submitted multiple times concurrently, which could happen for transfers with a number of segments that is smaller than the DMA controller's internal queue.

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.
