[PATCH 3/5] Tools: hv: address compiler warnings for hv_kvp_daemon.c

From: Vitaly Kuznetsov
Date: Tue Dec 09 2014 - 10:49:37 EST


This patch addresses two types of compiler warnings:
... warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
and
... warning: pointer targets in passing argument N of âkvp_...â differ in signedness [-Wpointer-sign]
