When xHC is asked to stop an endpoint it will save the position it stopped on in the endpoint or stream context. xhci driver needs to know if the controller stopped on the exact same TRB that the driver was asked to cancel as it then needs to move past the TD instead of turning the TD to no-op TRBs. xhci driver used to get the stopped position from a "stopped" transfer event before the stop endpoint command completed, but if the ring is already stopped, or in a halted or error state this event is missing. Get the stopped position from the endpoint or stream context instead Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
