CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	jbrassow at sourceware.org	2011-09-19 14:28:24

Modified files:
	lib/metadata   : mirror.c 

Log message:
	fix compiler warning.
	
	Compiler says variable may be used uninitialized.  It can't be, but we
	initialize the variable to NULL anyway.  Also, remove the double initialization
	of another variable.
