[PATCH] mutex subsystem, semaphore to completion: IDE ->gendev_rel_sem

The patch changes semaphores that are initialized as
locked to complete().

Source: MontaVista Software, Inc.

Modified-by: Steven Rostedt <rostedt@goodmis.org>

The following patch is from Montavista.  I modified it slightly.
Semaphores are currently being used where it makes more sense for
completions.  This patch corrects that.
