[ Upstream commit aa028141ab0bc62c44a84d42f09db35d82df82a2 ] In the pm8001_chip_sata_req() and pm80xx_chip_sata_req() functions, all tasks with a DMA direction of DMA_NONE (no data transfer) are initialized using the ATAP value 0x04. However, NCQ NON DATA commands, while being DMA_NONE commands are NCQ commands and need to be initialized using the value 0x07 for ATAP, similarly to other NCQ commands. Make sure that NCQ NON DATA command tasks are initialized similarly to other NCQ commands by also testing the task "use_ncq" field in addition to the DMA direction. While at it, reorganize the code into a chain of if - else if - else to avoid useless affectations and debug messages.

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.
