For all patches in the set, can you please run the tool
./devtools/check-git-log.sh [1], it checks for some common commit log
errors.
[1]
./devtools/check-git-log.sh checks the applied commits in the tree and
gets commit number to check as parameter:
"./devtools/check-git-log.sh -16" for this case.
