kunit: Fix missing kerneldoc comment

On X1E80100, GPIO interrupts for wakeup-capable pins have been broken since
the introduction of the pinctrl driver. This prevents keyboard and touchpad
from working on most of the X1E laptops. So far we have worked around this
by manually building a kernel with the "wakeup-parent" removed from the
pinctrl node in the device tree, but we cannot expect all users to do that.

Implement a similar workaround in the driver by clearing the wakeirq_map
for X1E80100. This avoids using the PDC wakeup parent for all GPIOs
and handles the interrupts directly in the pinctrl driver instead.

The PDC driver needs additional changes to support X1E80100 properly.
Adding a workaround separately first allows to land the necessary PDC
changes through the normal release cycle, while still solving the more
critical problem with keyboard and touchpad on the current stable kernel
versions. Bypassing the PDC is enough for now, because we have not yet
enabled the deep idle states where using the PDC becomes necessary.

If we trigger the bus rescan from sysfs, we'll try to lock the PCI rescan
mutex recursively and deadlock - the platform device will be populated and
probed on the same thread that handles the sysfs write.

Add a workqueue to the pwrctl code on which we schedule the rescan for
controlled PCI devices. While at it: add a new interface for initializing
the pwrctl context where we'd now assign the parent device address and
initialize the workqueue.

kunit_driver_create() accepts a name for the driver, but does not copy
it, so if that name is either on the stack, or otherwise freed, we end
up with a use-after-free when the driver is cleaned up.

Instead, strdup() the name, and manage it as another KUnit allocation.
As there was no existing kunit_kstrdup(), we add one. Further, add a
kunit_ variant of strdup_const() and kfree_const(), so we don't need to
allocate and manage the string in the majority of cases where it's a
constant.

However, these are inline functions, and is_kernel_rodata() only works
for built-in code. This causes problems in two cases:
- If kunit is built as a module, __{start,end}_rodata is not defined.
- If a kunit test using these functions is built as a module, it will
suffer the same fate.

This fixes a KASAN splat with overflow.overflow_allocation_test, when
built as a module.

Restrict the is_kernel_rodata() case to when KUnit is built as a module,
which fixes the first case, at the cost of losing the optimisation.

Also, make kunit_{kstrdup,kfree}_const non-inline, so that other modules
using them will not accidentally depend on is_kernel_rodata(). If KUnit
is built-in, they'll benefit from the optimisation, if KUnit is not,
they won't, but the string will be properly duplicated.

clang warns on this because it has an unannotated fall-through between
cases:

arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.

gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break. Odd.

of_platform_depopulate() doesn't play nicely with reused OF nodes - it
ignores the ones that are not marked explicitly as populated and it may
happen that the PCI device goes away before the platform device in which
case the PCI core clears the OF_POPULATED bit.

Unconditionally unregister the platform devices for child nodes when
stopping the PCI device.
