These patches replace commas by semicolons.  This was done using the
Coccinelle semantic patch (http://coccinelle.lip6.fr/) shown below.

This semantic patch ensures that commas inside for loop headers will not be
transformed.  It also doesn't touch macro definitions.

Coccinelle ensures that braces are added as needed when a single-statement
branch turns into a multi-statement one.

This semantic patch has a few false positives, for variable delcarations
such as:

LIST_HEAD(x), *y;

The semantic patch could be improved to avoid these, but for the moment
they have been removed manually (2 occurrences).
