Niklas Schnelle a8b5611ffe s390/pci: do not set affinity for floating irqs
commit 86dbf32da150339ca81509fa2eb84c814b55258b upstream.

with the introduction of CPU directed interrupts the kernel
parameter pci=force_floating was introduced to fall back
to the previous behavior using floating irqs.

However we were still setting the affinity in that case,
both in __irq_alloc_descs() and via the irq_set_affinity
callback in struct irq_chip.

For the former only set the affinity in the directed case.

The latter is explicitly set in zpci_directed_irq_init()
so we can just leave it unset for the floating case.

Fixes: e979ce7bce ("s390/pci: provide support for CPU directed interrupts")

README

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.
