What's the GCC warning? Please include in the commit text.

Also what's the implicit-fallthrough level you're using? 3? Can you file
a bug so GCC can update their regex to accept a comma in addition to
whitespace characters?

And maybe we can change the level to 2 or 1 in the kernel's makefile so
we don't need to patch comments for this.
