This reverts commit 983e6b2636f0099dbac1874c9e885bbe1cf2df05 which is
commit 8a2f11878771da65b8ac135c73b47dae13afbd62 upstream.

It wasn't needed and caused a build break on s390, so just revert it
entirely.

Pull filesystem freezing updates from Darrick Wong:

New code for 6.6:

* Allow the kernel to initiate a freeze of a filesystem. The kernel
and userspace can both hold a freeze on a filesystem at the same
time; the freeze is not lifted until /both/ holders lift it. This
will enable us to fix a longstanding bug in XFS online fsck.

ASoC: Improve coverage in default KUnit runs

Merge series from Mark Brown <broonie@kernel.org>:

We have some KUnit tests for ASoC but they're not being run as much as
they should be since ASoC isn't enabled in the configs used by default
with KUnit and in the case of the topology tests there is no way to
enable them without enabling drivers that use them. This series
provides a Kconfig option which KUnit can use directly rather than worry
about drivers.

Further, since KUnit is typically run in UML but ALSA prevents build
with UML we need to remove that Kconfig conflict. As far as I can tell
the motiviation for this is that many ALSA drivers use iomem APIs which
are not available under UML and it's more trouble than it's worth to go
through and add per driver dependencies. In order to avoid these issues
we also provide stubs for these APIs so there are no build time issues
if a driver relies on iomem but does not depend on it. With these stubs
I am able to build all the sound drivers available in a UML defconfig
(UML allmodconfig appears to have substantial other issues in a quick
test).

With this series I am able to run the topology KUnit tests as part of a
kunit --alltests run.

The PCI root bus is in this case created from ACPI description via
acpi_pci_root_add() -> pci_acpi_scan_root() -> acpi_pci_root_create() ->
pci_create_root_bus() where the last function is called with
parent=NULL. It indicates that no parent is present and then
bus->bridge->parent is NULL too.

Fix the problem by checking bus->bridge->parent in xen_dt_get_node() for
NULL first.
