via_save_pcictrlreg() should be called with host->lock held
as it writes to pm_pcictrl_reg, otherwise there can be a race

The same pattern is used in the function via_reset_pcictrl()

It is not necessary to use src/dst as an intermediate variable for
assignment operation; Delete src/dst intermediate variables to avoid
unnecessary variable declarations.

Hi Konstantin,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on linux/master]

support for userfaultfd file descriptors so that its creation and
movement can be controlled.
It has been demonstrated on various occasions that suspending kernel

A third option is added to 'unprivileged_userfaultfd' sysctl knob.
When the knob is set to 2, it allows unprivileged users to call
userfaultfd, like when it is set to 1, but with the restriction that
page faults from only user-mode can be handled. In this mode,
an unprivileged user (without SYS_CAP
userfaultfd handles page faults from both user and kernel code.
Add a new UFFD_USER_MODE_ONLY flag for userfaultfd(2) that makes
the resulting userfaultfd object refuse to handle faults from kernel
mode, treating these faults as if SIGBUS were always raised, causing
the kernel code to fail with EFA

Just fyi for anyone that cares:
A janitorial task for someone might be to use Julia's coccinelle
script below to convert the existing instances of commas that
separate statements into semicolons.

Critical data structures of security modules are currently not measured.
Therefore an attestation service, for instance, would not be able to
attest whether the security modules are always operating with the policies
and configuration that the system administrator had setup. The policies
