commit1c1dc8bda3upstream. When the ESTABLISH ccw does not complete within the specified timeout, try our best to cancel the ccw program that is still active on the device. Otherwise the IO subsystem might be accessing it even after the driver eg. called qdio_free(). Fixes:779e6e1c72("[S390] qdio: new qdio driver.")

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.
