Needs a changelog, even if it's similar to the topic.

Speaking of the topic, please run "git log --oneline drivers/pci/msi.c" and
make yours look similar to the others.  This doesn't really fix a syntax
issue; the existing code is syntactically correct.  It's only a style
issue.

I'd say something like:

  PCI/MSI: Remove unnecessary braces around single statements

  Per Documentation/CodingStyle, don't use braces around single statements.
