Well, what did I do wrong this time?

 - The patch is obviously correct and tested.
 - It is a two-liner, plus context.
 - It fixes exactly one thing.
 - The bug bothers people, and I gave links to reports.
 - It is an oops (a null pointer dereference).
 - No unrelated "trivial" fixes in there.
 - Follows SubmittingPatches rules, as far as I know.
 - Patch was produced by cherry-picking the commit named above from
   Linus's tree.
