[PATCH hyperpen] Fixed indentation, dropped trailing whitespaces

Manuel Reimer Manuel.Spam at nurfuerspam.de
Mon Nov 8 11:26:45 PST 2010


This patch shouldn't change the way the hyperpen driver works.
Anything, it does, is to fix the indentation and it drops some useless trailing 
whitespaces. Without this, the code is nearly unreadable.
I used this as reference: http://www.x.org/wiki/CodingStyle
