Hunk extracted from commit 70aacfe661
upstream.
If the sqpoll thread has died, the out condition doesn't remove the
waiting task from the waitqueue. The goto and check are not needed, just
make it a break condition after setting the error value. That ensures
that we always remove ourselves from sqo_sq_wait waitqueue.

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.
