  firmware_loader: Fix memory leak in firmware upload (2022-09-01 17:47:27 +0200)

Driver core fixes for 6.0-rc4

Here are some small driver core fixes for some oft-reported problems in
6.0-rc1.  They include:
  - a bunch of reverts to handle driver_deferred_probe_check_state()
    problems that were part of the 6.0-rc1 merge.
  - firmware_loader bugfixes now that the code is being properly tested
    and used by others
  - arch_topology fix
  - deferred driver probe bugfix to solve a long-suffering amba bus
    problem that many people have reported.

All of these have been in linux-next for a while with no reported
problems.

Entirely unrelated to this pull request, but since the diffstat made
that "drivers/base/dd.c" file stand out, I tried to look at what the
history of that odd name is.

And it's not obvious to me.

Very strange filename. Should it perhaps be named "device.c" or
"probe.c" or something more descriptive?

Not a huge deal, more of a passing thought inspired by that diffstat.

I think Pat named it and I always think of it as "device vs. driver".c
as it handles all of the device and driver interactions between binding
and unbinding and other fun logic there.  I'm all for a new name if
anyone has any ideas, "probe.c" is sane, but it also handles disconnect
logic.  "core.c" already has lots of device functions, so renaming it to
"device.c" would be confusing.  I don't know...

Yeah, in digging, Pat did this in commit 07e4a3e27fe4 ("[PATCH] Move
device/driver code to drivers/base/dd.c") way back in 2005 to get code
out of drivers/base/bus.c.

Naming is hard :)
