commit a4775a5f56be2c3f76eaab9a95421147a87adbb2
Author: Michael Opdenacker <michael.opdenacker at free-electrons.com>
Date:   Tue Feb 4 13:29:21 2014 +0100

    Kernel slides: simplify hello.c example
    
    - There was a missing space at the beginning of the second
      pr_alert string (the first one has no \n)
    
    - Put the code download URL in cgit, easier to keep in sync
    
    - Misc minor fixes
