Merge changes related to the runtime power management of devices for
6.9-rc1:

 - Simplify pm_runtime_get_if_active() usage and add a replacement for
   pm_runtime_put_autosuspend() (Sakari Ailus).

 - Add a tracepoint for runtime_status changes tracking (Vilas Bhat).

 - Fix section title markdown in the runtime PM documentation (Yiwei
   Lin).

* pm-runtime:
  Documentation: PM: Fix runtime_pm.rst markdown syntax
  PM: runtime: add tracepoint for runtime_status changes
  PM: runtime: Add pm_runtime_put_autosuspend() replacement
  PM: runtime: Simplify pm_runtime_get_if_active() usage

The '7. Generic subsystem callbacks' should be a section title, but
the markdown syntax is not adequate now.

Fix it so the chapter can be linked at docs.kernel.org correctly.

According to the context, 'pci_pm_suspend_noirq' is the right

Add __pm_runtime_put_autosuspend() that replaces
pm_runtime_put_autosuspend() for new users. The intent is to later
re-purpose pm_runtime_put_autosuspend() to also mark the device's last
busy stamp---which is what the vast majority of users actually need.

This is also described in pm_runtime_put_autosuspend() documentation.

There are two ways to opportunistically increment a device's runtime PM
usage count, calling either pm_runtime_get_if_active() or
pm_runtime_get_if_in_use(). The former has an argument to tell whether to
ignore the usage count or not, and the latter simply calls the former with
ign_usage_count set to false. The other users that want to ignore the
usage_count will have to explicitly set that argument to true which is a
bit cumbersome.

To make this function more practical to use, remove the ign_usage_count
argument from the function. The main implementation is in a static
function called pm_runtime_get_conditional() and implementations of
pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to
runtime.c.

Add a new description which covers the information about runtime EM.
It contains the design decisions, describes models and how they
reflect the reality. Remove description of the default EM. Add example
driver code which modifies EM. Add API documentation for the new feature
which allows to modify the EM in runtime.

As noted in the "Deprecated Interfaces, Language Features, Attributes,
and Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead
to values wrapping around and a smaller allocation being made than the
caller was expecting. Using those allocations could lead to linear
overflows of heap memory and other misbehaviors.

So, in the example code use the purpose specific kcalloc() function
instead of the argument size * count in the kzalloc() function.

At the same time, modify the translations accordingly.
