Tools: hv: kvp: eliminate 'may be used uninitialized' warning
[ Upstream commit 89eb4d8d25722a0a0194cf7fa47ba602e32a6da7 ] When building hv_kvp_daemon GCC-8.3 complains: hv_kvp_daemon.c: In function ‘kvp_get_ip_info.constprop’: hv_kvp_daemon.c:812:30: warning: ‘ip_buffer’ may be used uninitialized in this function [-Wmaybe-uninitialized] struct hv_kvp_ipaddr_value *ip_buffer; this seems to be a false positive: we only use ip_buffer when op == KVP_OP_GET_IP_INFO and it is only unset when op == KVP_OP_ENUMERATE. Silence the warning by initializing ip_buffer to NULL. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
