Oh, and I forgot to mention: Please follow the convention of
capitalizing the first word of the subject (use "git log --oneline
drivers/pci/controller/dwc/pcie-designware-host.c" to see what the
convention is).

Also, the commit log does not actually say what the patch *does*.
Please include an imperative statement about what it does in the
commit log.  https://chris.beams.io/posts/git-commit/ has good tips.
