But it's easy to fix it. Either drivers need suspend routines that are 
called without interrupts enabled, or they don't. The current situation 
is that the interface is broken regardless of which is the case - the 
situation with the patch is that the interface only stops working for 
drivers that need the suspend routine to be called with disabled 
interrupts.
