Come to think of it, it could be a problem if the comnpiler was silly and
built an entire temporary on the stack and the copied it over.  Hopefull it
won't do that.


From: Pekka Enberg <penberg@cs.helsinki.fi>

This patch addresses the following minor issues:

  - Typo in printk
  - Redundant casts
  - Use C99 struct initializers instead of memset
  - Parenthesis around return value
  - Use inline instead of __inline__
