Module name:	LVM2
Changes by:	zkabelac@sourceware.org	2011-01-06 10:45:41

Modified files:
	daemons/dmeventd: libdevmapper-event.c 

Log message:
	Remove dead assignment of 'ret' value
	
	Variable 'ret' assigned from _do_event() was actually not used and replaced with next
	assignment without any read of the returned value.
	
	Code is reformated - so the error path is put in the if() branch and normal
	code is put after the 'if' together with FIXME comment.
	
	FIXME lowprio: logging needs to be fixed in this code,
	- multiple log_errors are printed, stacks are missing...
