[PATCH 5/6] kconfig: don't allocate n+1 elements in temporary array

From: Yann E. MORIN
Date: Tue Jul 16 2013 - 16:40:57 EST


From: "Yann E. MORIN" <yann.morin.1998@xxxxxxx>

The temporary array that stores the search results is not NULL-terminated,
so there is no reason to allocate n+1 elements.
