One of the advantages of cpp support for me is the ability to remove the
redundant part of the command. In other words, perhaps remove the "150
->" since that information is part of the OMAP_GPIO() "call", leaving
just /* D6 LED */. I might have expected "D6" to be the label too, thus
removing any need for the comment.
