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. The only change compared to v3 is in the fourth patch where I modified a few more drivers to fix build failures. Some of them were found by build bots (thanks!), some of them I found myself using a regular expression search.
