The guest's AP configuration is cleared when the mdev is removed, so
userspace must be notified that the AP configuration has changed. To this
end, this patch:
* Removes call to 'signal_guest_ap_cfg_changed()' function from the
'vfio_ap_mdev_unset_kvm()' function because it has no affect given it is
called after the mdev fd is closed.
* Adds call to 'signal_guest_ap_cfg_changed()' function to the
'vfio_ap_mdev_request()' function to notify userspace that the guest's
AP configuration has changed before signaling the request to remove the
mdev.
Minor change - Fixed an indentation issue in function
'signal_guest_ap_cfg_changed()'
Fixes: 07d89045bf ("s390/vfio-ap: Signal eventfd when guest AP configuration is changed")

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 reStructuredText 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.
