NCQ NON DATA is an NCQ command with the DMA_NONE DMA direction and so a register-device-to-host-FIS response is expected for it. However, for an IO_SUCCESS case, mpi_sata_completion() expects a set-device-bits-FIS for any ata task with an use_ncq field true, which includes NCQ NON DATA commands. Fix this to correctly treat NCQ NON DATA commands as non-data by also testing for the DMA_NONE DMA direction.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
