The PCI core already ensures that the MSI[-X] state is correct when MSI[-X] is disabled. For MSI the reset state is all entries unmasked and for MSI-X all vectors are masked. S390 masks all MSI entries and masks the already masked MSI-X entries again. Remove it and let the device in the correct state.

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.
