I would personally do this as two patches, as you are touching a number of files and are doing two separate things here. As a rule of thumb, when the changelog text mentions two or more things that the patch does, the patch should be split up so that each part does one thing. After you do that, it also becomes easier to write a good subject line like "mark function as static" and "add missing includes", which tells you more about the patch than "silence warnings". It's quite likely that the nouveau maintainers are less picky than I am though, so if they want to apply the patch as-is Acked-by: Arnd Bergmann <arnd@xxxxxxxx> Otherwise please split and resend in a few days, in case there are other comments that need to be addressed.
