[ Upstream commit 62413199cd6d2906c121c2dfa3d7b82fd05f08db ] In case of SSP underflow allow the response frame IU to be examined for setting the response stat value rather than always setting SAS_DATA_UNDERRUN. This will mean that we call sas_ssp_task_response() in those scenarios and may send sense data to upper layer. Such a condition would be for bad blocks were we just reporting an underflow error to upper layer, but now the sense data will tell immediately that the media is faulty.

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.
