tracing: Remove unnecessary DEBUG_FS dependency (2019-11-22 16:19:13 +0100)

Driver core patches for 5.5-rc1

Here is the "big" set of driver core patches for 5.5-rc1

There's a few minor cleanups and fixes in here, but the majority of the
patches in here fall into two buckets:
- debugfs api cleanups and fixes
- driver core device link support for boot dependancy issues

The debugfs api cleanups are working to slowly refactor the debugfs apis
so that it is even harder to use incorrectly. That work has been
happening for the past few kernel releases and will continue over time,
it's a long-term project/goal

The driver core device link support missed 5.4 by just a bit, so it's
been sitting and baking for many months now. It's from Saravana Kannan
to help resolve the problems that DT-based systems have at boot time
with dependancy graphs and kernel modules. Turns out that no one has
actually tried to build a generic arm64 kernel with loads of modules and
have it "just work" for a variety of platforms (like a distro kernel)
The big problem turned out to be a lack of depandancy information
between different areas of DT entries, and the work here resolves that
problem and now allows devices to boot properly, and quicker than a
monolith kernel.

All of these patches have been in linux-next for a long time with no
reported issues.
