Now that libata does its own internal device power mode management through libata EH, the scsi disk driver will not issue START STOP UNIT commands anymore. We can receive this command only from user passthrough operations. So there is no need to consider the system state and ATA port flags for suspend to translate the command. Since setting up the taskfile for the verify and standby immediate commands is the same as done in ata_dev_power_set_active() and ata_dev_power_set_standby(), factor out this code into the helper function ata_dev_power_init_tf() to simplify ata_scsi_start_stop_xlat() as well as ata_dev_power_set_active() and ata_dev_power_set_standby().

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.
