Currently much indentation in this file is done with whitespaces instead of
tabs, which can make reading difficult, so fix this up.
Some other little minor tidy-up is done, but this file still has many other
checkpatch warnings (generally linelength > 80 or function arguments have
no identifier names).
All libsas code can be audited for checkpatch issues later.
