Linux kernel for uConsole
ffb1c820b8
When issing a hardreset to a SATA device when running IO, it is possible that abnormal CQs of the device are returned. Then enter error handler, it doesn't enter function hisi_sas_abort_task() as there is no timeout IO, and it doesn't set device as HISI_SAS_DEV_EH. So when hardreset by libata later, it actually doesn't issue hardreset as there is a check to judge whether device is in error. For this situation, actually need to hardreset the device to recover. So remove the check of sas_dev status in hisi_sas_I_T_nexus_reset(). Before we add the check to avoid the endless loop of reset for directly-attached SATA device at probe time, actually we flutter it for it, so it is not necessary to add the check now.

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.
