From: David Binder <david.binder@xxxxxxxxxx>
This patch ONLY touches comment lines, i.e., NO executable code is
affected.
* All functions worthy of documenting now use standard kerneldoc
formatting.
* Multi-line comments were tweaked so as to use appropriate conventions.
* Minor typos were corrected.
