How clang tooling was used to programatically do the clean up.
Solicit opinions on how to generally use clang tooling.

The clang warning -Wextra-semi-stmt produces about 10k warnings.
Reviewing these, a subset of semicolon after a switch looks safe to
fix all the time.  An example problem

void foo(int a) {
     switch(a) {
     	       case 1:
	       ...
     }; <--- extra semicolon
}

Treewide, there are about 100 problems in 50 files for x86_64 allyesconfig.
These fixes will be the upcoming cleanup.

coccinelle already does some of these.

For instance: scripts/coccinelle/misc/semicolon.cocci

Perhaps some tool coordination can be done here as
coccinelle/checkpatch/clang/Lindent call all be used
to do some facet or another of these cleanup issues.
