commitfb620ae73bupstream. The irq_raised completion used to detect the end of a test case is initialized when the test device is probed, but never reinitialized again before a test case. As a result, the irq_raised completion synchronization is effective only for the first ioctl test case executed. Any subsequent call to wait_for_completion() by another ioctl() call will immediately return, potentially too early, leading to false positive failures. Fix this by reinitializing the irq_raised completion before starting a new ioctl() test command.

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.
