* Broke up if statements so that the condition and the body are on
separate lines.
* Added spaces around commas and other operator characters.
* Removed extra blank lines.
* Added blank lines after declarations.
* Changed C99 comments into kernel style.
* Fixed checkpatch complaints where "{" char was on its own line but it
wasn't the start of a function.
