commitef2cb4f0ceupstream. In case the controller detected an error, the code took the chance to move all the queued (submitted) descriptors to the active (issued) list. This was wrong as if there were any descriptors in the submitted list they were moved to the issued list without actually issuing them to the controller, thus a completion could be raised without even fireing the descriptor.

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.
