From: Greg Kroah-Hartman
Date: Sat Jul 26 2014 - 15:24:28 EST


3.15-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ted Juan <ted.juan@xxxxxxxxx>

commit 6938ad40cb97a52d88a763008935340729a4acc7 upstream.

These two function's switch case lack the 'break' that make them always
return error.
