Pull USB fixes from Greg KH:
 "Here are some small USB fixes for 5.3-rc4.

  The "biggest" one here is moving code from one file to another in
  order to fix a long-standing race condition with the creation of sysfs
  files for USB devices. Turns out that there are now userspace tools
  out there that are hitting this long-known bug, so it's time to fix
  them. Thankfully the tool-maker in this case fixed the issue :)

  The other patches in here are all fixes for reported issues. Now that
  syzbot knows how to fuzz USB drivers better, and is starting to now
  fuzz the userspace facing side of them at the same time, there will be
  more and more small fixes like these coming, which is a good thing.

  All of these have been in linux-next with no reported issues"

Since commit ff9b45c5 ("kbuild: modpost: read modules.order instead
of $(MODVERDIR)/*.mod"), a module is no longer built in the following
pattern:

  [Makefile]
  subdir-y := some-module

  [some-module/Makefile]
  obj-m := some-module.o

You cannot write Makefile this way in upstream because modules.order is
not correctly generated. subdir-y is used to descend to a sub-directory
that builds tools, device trees, etc.

For external modules, the modules order does not matter. So, the
Makefile above was known to work.

I believe the Makefile should be re-written as follows:

  [Makefile]
  obj-m := some-module/

  [some-module/Makefile]
  obj-m := some-module.o

However, people will have no idea if their Makefile suddenly stops
working. In fact, I received questions from multiple people.

Show a warning for a while if obj-m is specified in a Makefile visited
by subdir-y or subdir-m.

I touched the %/ rule to avoid false-positive warnings for the single
target.

The modules.order files in directories visited by the chain of obj-y
or obj-m are merged to the upper-level ones, and become parts of the
top-level modules.order. On the other hand, there is no need to
generate modules.order in directories visited by subdir-y or subdir-m
since they would become orphan anyway.

The current implementation of need-builtin is false-positive,
for example, in the following Makefile:

  obj-m := foo/
  obj-y := foo/bar/

..., where foo/built-in.a is not required.

I removed the single target %.ko in commit ff9b45c5 ("kbuild:
modpost: read modules.order instead of $(MODVERDIR)/*.mod") because
the modpost stage does not work reliably. For instance, the module
dependency, modversion, etc. do not work if we lack symbol information
from the other modules.

Yet, some people still want to build only one module in their interest,
and it may be still useful if it is used within those limitations.
