Format your log message so it is no more than 80 characters wide (I like
72) and remove the gratuitous spacing on the second line.

Put a blank line between your log message and your Signed-off-by:

This patch is doing two things: adding blank lines and fixing
spaces/tabs in a line.  Break it up in to two patches.
