[v3,0/5] bus: Make remove callback return void

Message

Hello,

this is the final patch set for my effort to make struct
bus_type::remove return void.

The first four patches contain cleanups that make some of these
callbacks (more obviously) always return 0. They are acked by the
respective maintainers. Bjorn Helgaas explicitly asked to include the
pci patch (#1) into this series, so Greg taking this is fine. I assume
the s390 people are fine with Greg taking patches #2 to #4, too, they
didn't explicitly said so though.

The last patch actually changes the prototype and so touches quite some
drivers and has the potential to conflict with future developments, so I
consider it beneficial to put these patches into next soon. I expect
that it will be Greg who takes the complete series, he already confirmed
via irc (for v2) to look into this series.

In the last round I failed to send the cover letter to all affected
people, sorry for that, this should be fixed now.

Best regards
Uwe

Changes since v2:
 - Add several acks/review tags
 - Include patch #1 explicitly
 - rebase to v5.14-rc1, build test on amd64, arm64 and s390 using
   allmodconfig
